Lately, frequent offshore oil spills and the limitations of traditional oil–water separation membranes in balancing selectivity and permeability have driven the development of innovative membrane technologies for the efficient treatment of oily wastewater. In this study, a durable and recyclable Acrylonitrile–Butadiene–Styrene (ABS) membrane was fabricated using 3D printing, subsequently sulfonated via radiation-induced grafting, and further modified with in situ mineralization to prepare β-FeOOH@ABS membrane. The β-FeOOH@ABS membrane exhibited excellent hydrophilicity and oleophobicity compared to bare hydrophobic ABS membrane, with a water contact angle of 16° and an underwater oil contact angle of 162°. Under gravity-driven conditions, the β-FeOOH@ABS membrane achieved a separation efficiency exceeding 99.78 % across five different oil–water mixtures, along with an exceptionally high flux of 2.93 × 10 5 L·m -2 ·h -1 , attributed to stable hydration layer formed via β-FeOOH nanorods. Combined 100 cycles durability tests and XDLVO theoretical analysis, it was found that the β-FeOOH@ABS membrane showed excellent long-term stability and anti-fouling performance with high flux recovery of 99.41 % and separation efficiency of 99.83 %, originating from its enhanced fouling resistance. The photocatalytic property of β-FeOOH nanorods also endowed the β-FeOOH@ABS membrane with superior catalytic performance. This work underscores the significant potential of novel β-FeOOH@ABS membranes for advanced oil–water separation applications.

Summary Two novel phosphorus-nitrogen-silicon copolymers (DDSQ-N-P-yne and DDSQ-N-P-ene) were synthesized by hydrosilylation reaction with DDSQ and DOPO derivatives. DOPO derivatives with different end groups were designed and synthesized to compare the flame retardancy and compatibility of phosphorus-nitrogen-silicon copolymers by different linkers between DDSQ and DOPO derivatives. The synthesized copolymers have been evidenced by 1 H, 29 Si nuclear magnetic resonance, and gel permeation chromatography and then introduced into polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) alloy to study their flame retardancy and explore whether they exhibit a synergistic effect on the flame retardancy. The flame-retardant properties of DDSQ-N-P-yne (or ene) systems as well as the morphology were investigated in detail by using limiting oxygen index, thermogravimetric analysis, UL-94, microcalorimeter, energy dispersive X-ray, and scanning electron microscopy, respectively. When DDSQ-N-P-yne (or ene) content is 10 wt%, the composites of PC/ABS are identified to be very effective according to limiting oxygen index, UL-94, and microcalorimeter. The microstructures of the char were investigated by scanning electron microscopy, and the results indicated a tight and compact graphitized layer shaped, which plays an important role in improving the excellent thermal stability and flame retardancy of PC/ABS alloy.

With the continuous development of modern electronic equipment, thermal management of electronic devices has become the focus of attention due to the energy consumption. As an important part of thermal management system, it is necessary to develop an electrical equipment shell with both superior thermal conductivity and mechanical properties for better thermal management performance. However, it is very difficult to balance the relationship between thermal conductivity and mechanical properties of thermal conductive polymer composites . Increasing filling content of thermal conductive fillers would lead to heavy damage of mechanical properties. In this paper, we construct a bi-continuous structure to solve this problem. The ABS phase provides thermal conductivity enhancement, while the PC phase is responsible for mechanical property maintaining. A highest thermal conductivity of 0.476 W/(m⋅K), 138% higher than that of pure PC, can be obtained after optimum design of formulation and processing conditions. Meanwhile, the mechanical properties of PC/ABS composite are also enhanced comparing with filled-PC. Moreover, the reported PC/ABS composite has excellent electrical insulation and dielectric properties . Overall, our PC/ABS composites with simultaneous enhanced thermal conductivity and mechanical properties are of great prospect as electrical equipment shells for efficient thermal dissipation .

In consideration of inherent high hysteretic losses resulting in low energy efficiency for ferroelectric polymer, linear dielectric acrylonitrile butadiene styrene (ABS) with low price and good film property is adopted as optimal polymer matrix. Synchronously, representative ferroelectric barium titanate (BT) nanoparticles with high dielectric constant are selected as the nanofiller. To weaken the surface energy of BT nanoparticles and boost the interfacial interaction, polar polymer (poly[bis(4-cyanophenyl) 2-vinylterephthalate] (PBCN)) is employed as organic coatings to regulate interfacial property. Consequently, core–shell structured PBCN@BT nanoparticles were synthesized by means of reversible addition-fragmentation chain transfer polymerization combined with thiol-ene click reaction and the corresponding ABS-based nanocomposites were prepared. In consequence, discharge energy density increased from 3.2 J/cm 3 for the pure ABS film to 4.5 J/cm 3 for the 0.5 vol%-PBCN@BT/ABS nanocomposites. Meantime, a high energy efficiency of 76% was found. This discovery is of great significance for the development of excellent performance ABS-based dielectric composites.

The poor heat resistance of acrylonitrile-butadiene-styrene copolymer (ABS) is a significant limitation that restricts its application in various fields, including automotive, electronic devices and other fields. To address this issue, we employed a strategy involving the crosslinking of a macromolecular heat-resistant agent to enhance the heat resistance of ABS. Poly(N-(4-fluorophenyl) maleimide-alt-triallyl isocyanurate) (PFT), a reactive heat-resistant agent known for its rigid and reactive structures, was selected for this purpose. ABS/PFT composites were prepared by subjecting them to γ-ray irradiation, resulting in crosslinking through a solid-state interfacial reaction (SSIR) between PFT and ABS. The results show that the heat distortion temperature ( HDT ), glass transition temperature ( T g ), tensile strength and bending strength of the irradiated ABS/PFT (i-ABS/PFT) composites increased by 23.86%, 23.35%, 20.0% and 9.0%, respectively compared to pure ABS. Furthermore, ABS/PFT composites with SSIR exhibit the highest heat resistance, T g and HDT compared to non-SSIR ABS. The work presented in this paper provides a new direction for the heat-resistant modification of ABS and will expand its application in new fields.

Recycled acrylonitrile–butadiene–styrene (rABS) and recycled high impact polystyrene (rHIPS) are vital components of waste electrical and electronic equipment (WEEE) plastics, playing crucial roles in the recycling process. This paper utilized sodium chlorite (NaClO 2 ) to modify the surfaces of rABS and rHIPS, followed by flotation to separate the two types of plastics. X-ray photoelectron spectroscopy (XPS) test confirmed that the number of hydrophilic groups introduced on the rABS surface was more than that of rHIPS after surface modification. Through contact angle measurements, scanning electron microscope (SEM), and atomic force microscopy (AFM), it was confirmed that the modification on the rABS sample surface altered its microstructure and enhanced its surface wettability. The sodium chlorite concentration, modification temperature, and modification time significantly affected the floating percentage of rABS and rHIPS. The optimal surface modification conditions were determined to be a sodium chlorite concentration of 0.08 mol L -1 , a modification temperature of 70 °C, and a modification time of 60 min. Under these conditions, efficient separation of rABS and rHIPS was achieved, with floating percentage of 3.62 and 96.39%, respectively. Therefore, surface modification using sodium chlorite can be utilized to facilitate the flotation separation of rABS and rHIPS.

Microfibrillated cellulose (MFC) has attracted increasing attention as a sustainable reinforcement for polymer composites. However, when incorporated into hydrophobic thermoplastics such as acrylonitrile–butadiene–styrene (ABS), MFC often improves tensile strength but significantly reduces elongation at break. To address this challenge, we designed a surface modification strategy for MFC. Leaf bleached kraft pulp (LBKP) was first carboxyethylated and mechanically fibrillated to produce carboxyethylated MFC (C-MFC), which was subsequently amidated with octadecylamine (ODA) to obtain hydrophobized octadecylamine-modified carboxyethyl MFC (OC-MFC). Composite films of OC-MFC/ABS were fabricated by solution casting followed by hot pressing. The structures and properties of MFC, C-MFC, OC-MFC, and OC-MFC/ABS composites were systematically characterized using laser particle size analysis, FTIR, dynamic water contact angle, tensile testing, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The results demonstrated that ODA modification effectively increased the hydrophobicity of MFC, leading to improved dispersion and interfacial compatibility with the ABS matrix. Mechanical testing revealed that the incorporation of 0.5–1 wt% OC-MFC into ABS composite films preserved the tensile strength, while significantly enhancing. Morphological observations further supported the toughening effect of OC-MFC. These findings highlight a practical strategy for toughening ABS through the incorporation of surface-modified MFC, providing insights into the design of high-performance bio-based thermoplastic composites.

An antistatic agent, poly(aniline-amino-carbon nanotube) (PANI-A-CNT), was prepared using emulsion polymerization. Melt‑blending of ABS resin with C 12 mimBr and PANI‑A‑CNT yielded the antistatic PANI‑A‑CNT/IL/ABS composites. A parallel set of IL‑free blends was also made to serve as a control. Transmission electron microscopy (TEM) analysis showed that C 12 mimBr promotes the dissociation of carbon nanotube bundles. This effect enhances the dispersion uniformity of the PANI‑functionalized carbon nanotubes in the ABS substrate. As a result, a more complete conductive network forms within the ABS resin, which enhances the antistatic performance of the composite. With 4 wt% PANI‑A‑CNT and 6 wt% C 12 mimBr incorporated, the resulting composite showed a surface resistivity of 6.8 × 10⁸ Ω in the resistance measurements. The addition of C 12 mimBr reduced the surface resistance by 24.4%. Mechanical property tests showed that the addition of C 12 mimBr also improves the mechanical properties of PANI-A-CNT/ABS. Thus, the application value of the ABS antistatic composite is ensured.

In this study, the watersoluble epoxy resin was prepared via the ring-opening reaction between diethanolamine and epoxy resin. The modified resin mixed with graphene oxide (GO) as a sizing agent was coated onto carbon fiber (CF) and then the GO-CF reinforced acrylonitrile-butadienestyrene
(ABS) composites were prepared. The influences of the different contents of GO on CF and CF/ABS composite were explored. The combination among epoxy, GO sheets and maleic anhydride grafted ABS (ABSMA) showed a synergistic effect on improving the properties of GO-CF and GO-CF/ABS composite.
The GO-CF had higher single tensile strength than the commercial CF. The maximum ILSS of GO-CF/ABS composite obtained 19.2% improvement as compared with that of the commercial CF/ABS composite. Such multiscale enhancement method and the synergistic reinforced GO-CF/ABS composite show good
prospective applications in many industry areas.

Acrylonitrile-butadiene-styrene copolymer (ABS) is a kind of engineering plastic with excellent comprehensive properties, and is widely used in various industries. ABS can be converted into aromatics, aliphatics, and nitriles compound during thermal degradation, but the evolutionary mechanism of these degradation products remains unclear. In this article, ABS dimer, polyacrylonitrile (PAN), polybutadiene (PB), and polystyrene (PS) tetramer are selected as model compounds to investigate the evolution mechanism of the main pyrolysis products by using density functional theory method. The results show that the concerted reaction of HCN elimination by branched chain cleavage has a high reaction energy barrier and may be difficult to occur. The primary reaction pathway is the radical reaction involving the direct cleavage of the C butadiene -C acrylonitrile bond in the main chain, with an energy barrier of 287.1 or 286.3 kJ/mol. The two radicals generated by the initial pyrolysis can undergo further reactions, including β -scission, intramolecular hydrogen transfer, and dehydrogenation reactions. These reactions ultimately lead to the formation of the main products, such as styrene, acrylonitrile, butadiene, α -methylstyrene, and isopropylbenzene. The thermal degradation processes of ABS are investigated at 400, 500, and 600 ℃ by Py-GC/MS analysis. The experimental results of pyrolysis can effectively verify the rationality of the theoretical inference. Based on toxicity assessments, the acute and chronic toxicity of MC4 to aquatic organisms are severe. In addition, the toxicity of the degradation products is lower than that of MC4. These findings indicate that the toxicity of the products to aquatic organisms is significantly reduced.

In this study, the copolymers of methyl methacrylate-co-glycidyl methacrylate (MGD) with different epoxy contents and molecular weights, the styrene-co-glycidyl methacrylate (SGD) and methyl methacrylate-co-maleic anhydride (MAD) were synthesized. The synthesized copolymers, styrene-co-maleic anhydride (SMA) and styrene-acrylonitrile-co-glycidyl methacrylate (SAG) were used as compatibilizers to enhance the impact strength of the acrylonitrile butadiene styrene/poly(butylene terephthalate) (ABS/PBT). The effects of differences in the structure, reactive group type, and molecular weight of the compatibilizers on the mechanical properties, phase morphology, melt viscosity, thermal stability, and melting temperature of the blend were studied. The results showed that functionalized copolymers were successfully synthesized with high monomer conversions. Addition of the functionalized copolymers increased melt viscosity but did not considerably affect thermal stability, tensile strength, flexural strength and melting temperature of the ABS/PBT blends. The compatibilizers improved the dispersion of the PBT phase and prevented brittle fracture, thereby increasing the impact strength of the blend. Among the studied compositions, the ABS/PBT/MGD-5 blend exhibited the highest impact strength of 25.8 kJ/m 2 and an appropriate melt flow index of 19.1 g/10 minutes. The compatibilizer should have an appropriate molecular weight to improve the interface bonding force. Regarding the melting viscosity, the reactive group content and compatibilizer dosage should be adjusted to ensure high impact strength.
