Acrylonitrile–butadiene–styrene (ABS) composites with less smoke and toxicity hazards (e.g., HCN and NO x ) emission are highly demanded. As a common smoke suppressant, zinc hydroxystannate (ZHS) has been used in various polymers, while the high content, special cube shape and agglomeration restrict its development. To solve these problems, MXene (Ti 3 C 2 T x ) nanosheets were utilized to wrap ZHS nanoparticles (Ti 3 C 2 T x -PDA-ZHS) to improve the dispersion and compatibility of ZHS nanoparticles in ABS, in which polydopamine (PDA) was used as a binder to combine ZHS and MXene nanosheets. Accordingly, the prepared ABS/Ti 3 C 2 T x -PDA-ZHS nanocomposites showed the enhanced properties: (1) ABS/Ti 3 C 2 T x -PDA-ZHS exhibited a 69.7% increase in elongation at break compared to ABS/ZHS at a 2 mass% loading. (2) Owing to the synergistic effect of MXene and ZHS, Ti 3 C 2 T x -PDA-ZHS provided excellent inhibition on heat and toxic gas release during combustion (a reduction of approximately 17.5%, 34.5%, 19.1% and 20.0% of peak heat release rate, HCN, NO and NO 2 , respectively). (3) The smoke density decreased from 525.6 for neat ABS to 423.2 for ABS/Ti 3 C 2 T x -PDA-ZHS with a reduction of 19.5%, and the light transmittance of ABS/Ti 3 C 2 T x -PDA-ZHS (37.7%) was much higher than that of pure ABS (21.2%) at 240 s. Therefore, Ti 3 C 2 T x -PDA-ZHS showed a great enhancement in flammability, toxicity and smoke release reduction of ABS, potentially overcoming the weakness with improved diversity in future applications.

Copper films were grown on (3-Mercaptopropyl)trimethoxysilane (MPTMS), (3-Aminopropyl)triethoxysilane (APTES) and 6-(3-(triethoxysilyl)propylamino)-1,3,5- triazine-2,4-dithiol monosodium (TES) self-assembled monolayers (SAMs) modified acrylonitrile-butadiene-styrene (ABS) substrate via electroless copper plating. The copper films were examined using scanning electron microscopy (SEM) and X-ray diffraction (XRD). Their individual deposition rate and contact angle were also investigated to compare the properties of SAMs and electroless copper films. The results indicated that the formation of copper nuclei on the TES-SAMs modified ABS substrate was faster than those on the MPTMS-SAMs and APTES-SAMs modified ABS substrate. SEM images revealed that the copper film on TES-SAM modified ABS substrate was smooth and uniform, and the density of copper nuclei was much higher. Compared with that of TES-SAMs modified resin, the coverage of copper nuclei on MPTMS and APTES modified ABS substrate was very limited and the copper particle size was too big. The adhesion property test demonstrated that all the SAMs enhanced the interfacial interaction between copper plating and ABS substrate. XRD analysis showed that the copper film deposited on SAM-modified ABS substrate had a structure with Cu(111) preferred orientation, and the copper film deposited on TES-SAMs modified ABS substrate is better than that deposited on MPTMS-SAMs or APTES-SAMs modified ABS resins in electromigrtion resistance.Keywords:ABS resin;SAMs;electroless copper film;heterocyclic silane

PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) alloy has poor mechanical properties due to its poor compatibility and weak interfacial adhesion, which limits its application range. Therefore, it is necessary to compatibilize and modify the PC/ABS alloy to improve the compatibility and enhance the interfacial adhesion of the two phases. Reactive compatibilizers are frequently utilized to enhance the compatibility of incompatible polymer blends. However, traditional reactive compatibilizers often form graft copolymers with asymmetric molecular structure during melt blending, which frequently "migrate in" and "migrate out" under the influence of shear force, leading to a decrease in the compatibilization efficiency of compatibilizers. In this work, ethylene-maleic anhydride alternating copolymer (ZeMac) with more reactive sites was used as a reactive compatibilizer, and amino-terminated polystyrene (PS–NH 2 ) with good compatibility with ABS was synthesized via free radical polymerization. Combined with the difference of affinity between PC, ABS and ZeMac, and the difference of reactivity between PC, PS-NH 2 and ZeMac, a double-comb compatibilizer was constructed in-situ at the interface of the two phases by changing the blending sequence of raw materials in the melt blending process. Firstly, PC was blended with ZeMac, and then blended with ABS and PS-NH 2 to prepare (PC/ZeMac-1)/(ABS/PS-NH 2 -1) alloy with excellent comprehensive properties. Compared with PC/ABS alloy, the notched impact strength of (PC/ZeMac-1)/(ABS/PS-NH 2 -1) alloy increased from 62.0 kJ/m 2 to 90.2 kJ/m 2 , increased by 45 %. It can be seen from the microstructure of the cyclic tensile section that the debonding phenomenon of the PC/ABS alloy interface gradually weakened with the addition of ZeMac and PS-NH 2 , which proved that the compatibility of PC and ABS phases was improved. This study provides a certain reference value for the design of high-efficiency compatibilizers and the preparation of high-performance composites.

In the present study, the low pollution acidic potassium permanganate system has been used in the study of its micro-etching effect on polycarbonate-acrylonitrile butadiene styrene (PC-ABS). Prior to micro-etching using a N methyl pyrrolidone (NMP)-glycol butyl ether solution was used as the swelling system of PC-ABS. Reasonable swelling conditions were determined, a 2-min expansion period at a temperature of 35°C with an NMP concentration of 80%. After the swelling processes, the effects of the volume ratio of V H 2 O : V H 2 S O 4 , micro-etching temperature, and micro-etching duration on the PC-ABS surface morphology, surface roughness, surface hydrophilicity, and peel strength, have been investigated. It was finally determined that the best micro-etching effect could be obtained by reacting at V H 2 O : V H 2 S O 4 = 1:2 and a temperature of 60°C for 25 min. The surface of the PC-ABS copolymers was characterized by x-ray photoelectron spectroscopy, atomic force microscopy, and Fourier-transform infrared spectroscopy. The results showed that the micro-etching process changed the morphology of the PC-ABS surface and generated cavities. In addition, the surface roughness increased from the initial R a = 9.69 to R a = 197 nm. Also, the water contact angle on the PC-ABS surface decreased from 92.2° to 28.6°, and the peel strength increased to 0.98 kN/m.

Acrylonitrile-butadiene-styrene (ABS), as one of the most widely used engineering plastics, suffers from the problem of serious flammability and low mechanical strength . To address such an intractable challenge, herein, we report the design of a graphene-based multifunctional additive (Sb-Mo/Br-rGO) via the bromination followed by precipitating antimony molybdenum. The surface functionalization enables Sb-Mo/Br-rGO to homogeneously disperse within the ABS matrix through facile melt-blending. The incorporation of 5 wt% Sb-Mo/Br-rGO leads to a 31% increase in tensile strength and 73% increase in elastic modulus relative to the ABS bulk. In addition to significant enhancement in thermal stability, the inclusion of 5 wt% Sb-Mo/Br-rGO significantly delays the time to ignition of ABS by 12 s, and noticeably reduces the peak heat release rate (PHRR) and total smoke production (TSP) by 45% and 54%, respectively. Such improved performance portfolio is primarily because the mechanical reinforcing and thermal barrier effect of graphene nanosheets , the flame retardant effect of bromine/antimony, and the smoke suppression action of antimony molybdenum. This work provides an innovative methodology for the design of multifunctional additives to create high-performance polymeric materials with high strength and low flammability , thus contributing to improving the quality of life.

TG analysis, kinetic model and fixed-bed experiments were applied in this study to explore the synergistic effect of rape straw (RS) and acrylonitrile-butadiene-styrene copolymer (ABS) in the co-catalytic pyrolysis. The results showed that the preferential pyrolysis of RS was favorable for the formation of some active radicals and decreased the pyrolysis temperature of ABS from about 400 °C to 350 °C. As the mixing ratio of ABS rose, the temperature range of co-pyrolysis decreased gradually. The interaction between the free radicals generated by RS and ABS was effectively promoted with the addition of HZSM-5, and also the aromatization was accelerated. The temperature range of co-pyrolysis was decreased from 350 °C to 400 °C–340 °C–380 °C. The Flynn-Wall Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) were used to build the kinetics model, and revealed that the activation energy of co-pyrolysis system reached the bottom with the mixing ratio was 1:1, indicating the strongest synergistic effect at this point. The synergistic action was revealed from the kinetic analysis. In the fixed-bed test, the yield of liquid phase (54.15 %) and monocyclic aromatic hydrocarbons (MAHs) (32.87 %) peaked at the mixing ratio of 1:1, at which the synergistic effect inhibited the conversion to polycyclic aromatic hydrocarbons (PAHs).

Interface optimization in preparing natural fiber based biocomposite becomes a key factor that determines overall properties, especially mechanical performance. The solution for upgrading interfacial adhesion stemmed from polar fiber and nonpolar polymer remains unclear. Here, a kind of pulp fiber/acrylonitrile-butadiene-styrene (ABS) composite with content ratio of 1:1 was fabricated by functionalizing the cellulose fiber to coordinate interaction between fiber and ABS. With addition of 5 wt % polyacrylamide (PAM) there existed an interlinked three-element structure in composite. Three types of treatment to cellulose fiber, including alkali immersion, pivaloyl chloride grafting for 10 h and 20 h were conducted. Pulp fiber that was treated with alkali for one hour, followed by pivaloyl chloride reaction for ten hours, proved to be effective for interfacial adhesion. X-ray Photoelectron Spectroscopy (XPS) analysis reveals 21.9% of carbonyl and 12.1% of ester function in this fiber, which corresponds to oxidation and grafting. For its composite SEM picture displays that most of cellulose fiber are rooted in ABS and evident traces of tearing or fracture can be observed after tension test. DMA test indicates that this modified pulp fiber/ABS composite exhibits great compatibility, because of combined loss modulus peak ranging from 80 °C to 100 °C. Moreover, the well miscible composite has a tensile strength of 58.1 MPa and elastic modulus of 2515 MPa, increasing by nearly 50% and 60% from those of pure ABS, respectively.Keywords:ABS;modification;interfacial adhesion;compatibility;interlinked structure

Organic-inorganic hybrid particles have been prepared by grafting styrene maleic anhydride copolymer (SMA) onto reactive amino-modified silica nanoparticles. The SMA modified SiO 2 (SMA-SiO 2 ) was incorporated into polycarbonate (PC)/acrylonitrile-butadiene-styrene (ABS) composites (4:1, wt%/wt%) with bisphenol A bis (diphenyl phosphate) (BDP) to simultaneously improve the mechanical properties and flame retardancy. The mechanical properties of the sample containing SMA-SiO 2 are apparently improved compared with that of samples containing unmodified SiO 2 . It is found that SMA-SiO 2 tends to distribute at the phase interface of PC/ABS, and therefore improves the compatibility between PC and ABS . Besides, the peak of heat release rate (PHRR) and the total smoke production (TSP) of the PC/ABS composites are decreased by the presence of SMA-SiO 2 . It is suggested that SMA-SiO 2 can form a flame retarding shell at the phase interface to protect ABS. In summary, both the mechanical properties and flame retardancy of PC/ABS composites are significantly improved due to the selective distribution of SMA-SiO 2 .

Traditional microwave absorbing materials struggle to balance wideband absorption with mechanical properties, particularly in multifunctional applications. This study explores the effects of short carbon fibers (CF), cerium dioxide (CeO 2 ), and reduced graphene oxide (rGO) on the electromagnetic and mechanical properties of 3D-printed composites. The ABS@CF/CeO 2 /rGO composite with a thickness of 2.2 mm exhibited exceptional microwave absorption, achieving an effective absorption bandwidth (EAB) of 6.6 GHz and a minimum reflection loss (RL min ) of −40.9 dB. The Whale Optimization Algorithm (WOA) was employed to design a load-bearing, microwave-absorbing superstructure, which significantly improved wideband absorption. Experimental results confirmed the superstructure’s isotropy and wide-angle absorption capabilities. The calculated electromagnetic parameters were applied to evaluate the radar cross-section (RCS) of large targets, demonstrating enhanced stealth performance for unmanned aerial vehicles (UAVs). Mechanical tests revealed that rGO improved interlayer bonding strength, while CF negatively impacted bending performance. The superstructure also showed excellent mechanical stability in load-bearing tests, underscoring its potential for practical engineering applications. This study offers insights into designing advanced composite materials with balanced electromagnetic and mechanical properties, guiding future multifunctional material development.

The nanomaterials have been deeply explored as flame retardants for various polymeric materials due to their multifunctionality, but they often fail to significantly increase the limiting oxygen index (LOI) and vertical burning UL-94 rating, thus unable to meet industrial needs (LOI>27.0 % and UL-94 V-0 rating). Herein, we fabricated a cerium/phosphorus-doped g-C 3 N 4 (Ce/P-CN) nanohybrid as a multifunctional high-efficiency fire retardant for acrylonitrile–butadiene–styrene (ABS). The Ce/P-CN nanoflakes featured a strengthening effect towards ABS, 10 wt% of which increased the tensile strength of ABS/(Ce/P-CN) by 33.8 %. Meanwhile, the ABS/(Ce/P-CN) nanocomposites showed remarkably enhanced high-temperature stability and carbonization performances relative to virgin ABS. Ce/P-CN simultaneously improved the anti-ignition, fire retardancy and smoke suppression of ABS due to the barrier effect of g-C 3 N 4 nanoflakes and the catalytic carbonization effect of cerium and phosphorus. Notably, adding 10 wt% Ce/P-CN increased the LOI and UL-94 rating of ABS to 28.6 % and V-0, respectively, demonstrating its high flame-retardant efficiency. Thus, the high flame-retardant efficiency and multifunctionality enable Ce/P-CN to outperform previous flame retardants for ABS. This work offers a novel strategy for the development of high-efficiency g-C 3 N 4 nanoflakes, which endow ABS with improved mechanical robustness and fire retardancy and show broad industrial prospects.

Summary Two kinds of novel silicon-phosphorus linear polymers were synthesized by the hydrosilylation reaction of double-decker-shaped silsesquioxane (DDSQ) and 9,10-dihydro-9-oxa-10- phosphaphenanthrene-10-oxide (DOPO) derivatives and characterized using 1 H NMR, 31 P NMR, and 29 Si NMR. Flame-retardant polycarbonate/acrylonitric-butadiene-styrene (PC/ABS) blends were prepared with different contents of silicon-phosphorus linear polymers. The flame-retardant properties of silicon-phosphorus linear polymers as well as the morphology were investigated in detail by using thermogravimetric analysis (TGA), limiting oxygen index (LOI), (Underwriters Laboratory) UL-94, microscale combustion calorimetry (MCC), and scanning electron microscopy (SEM), respectively. The silicon-phosphorus linear polymers containing DDSQ and DOPO units can synergistically improve the flame retardancy and thermal stability of PC/ABS blends. Flame-retardant polymers with different linkers between DDSQ and phosphate units show comparable effect on the flame retardancy of PC/ABS.

In this study, a reactive hindered phenol antioxidant, 3,5-di- tert -butyl-4-hydroxyphenyl methyl isobutylene ester (DBHMIE), was synthesized and used to improve the antioxidant performance of ABS (acrylonitrile-butadiene-styrene terpolymer) resin. The chemical structure of DBHMIE was determined with Fourier transform infrared spectroscopy, 1 H nuclear magnetic resonance (NMR), and 13 C NMR spectroscopy. Moreover, the effects of the DBHMIE content on the antioxidant capabilities, thermal stabilities, tensile strengths, impact strengths, and morphologies of the ABS/antioxidant systems were investigated. The results indicated that the oxidation induction temperatures of the systems increased from 229.7 to 245.4°C as the DBHMIE content was increased from 0 to 0.5 wt%. The 5% mass loss temperature of the system was increased from 338.4 to 347.8°C by the addition of 0.3 wt% DBHMIE. The impact strengths of the systems increased with increasing DBHMIE content up to 0.1 wt% and then decreased. The addition of DBHMIE did not significantly affect the tensile strength of the ABS resin. SEM images showed that the DBHMIE was uniformly distributed in the ABS resin at low DBHMIE contents and agglomerated at high DBHMIE contents.
