Emulsion polymerization was used to create composites of polyaniline-amino-carbon nanotubes (PANI-A-CNT). Fourier transform infrared spectroscopy (FT-IR) was used to examine the chemical bonding properties of PANI and carbon nanotubes in composite materials. Transmission electron microscopy (TEM) was used to confirm that the PANI layer on the core-shell structure of PANI-A-CNT material was nanoscale in size. In order to assess the impact of various carbon nanotube contents on the electrostatic and mechanical properties of the composites, pristine carbon nanotube/ABS (p-CNT/ABS) and PANI-A-CNT/ABS composites were prepared. The mass fractions of PANI and CNT in PANI-A-CNT were 93.7 and 6.3 wt%, respectively, according to thermogravimetric analysis (TGA); hence, 4 wt% of PANI-A-CNT included 0.3 wt% CNT and 3.7 wt% PANI. The surface resistance test revealed that the PANI-A-CNT/ABS composite with 4 wt% PANI-A-CNT has a surface resistance of 10 8 Ω, which is one time less than the surface resistance of the p-CNT/ABS composite with 4 wt% p-CNT. Moreover, PANI-A-CNT/ABS composite (0–4 wt% PANI-A-CNT) has stronger tensile and impact properties than p-CNT/ABS composite (0–4 wt% p-CNT), expanding the range of applications for ABS resin.

A biology-inspired approach was utilized to functionalize hexagonal boron nitride (h-BN), to enhance the interfacial interactions in acrylonitrile-butadiene-styrene copolymer/boron nitride (ABS/BN) composites. The poly (dopamine), poly (DOPA) layer, was formed on the surface of BN platelets via spontaneously oxidative self-polymerization of DOPA in aqueous solution. The modified BN (named as mBN) coated with poly (DOPA) was mixed with ABS resin by melting. The strong interfacial interactions via π-π stacking plus Van der Waals, both derived from by poly (DOPA), significantly promoted not only the homogeneous dispersion of h-BN in the matrix, but also the effective interfacial stress transfer, leading to improve the impact strength of ABS/mBN even at slight mBN loadings. A high thermal conductivity of 0.501 W/(m·K) was obtained at 20 wt% mBN content, reaching 2.63 times of the value for pure ABS (0.176 W/(m·K)). Meanwhile, the ABS/mBN composites also exhibited an excellent electrical insulation property, which can be expected to be applied in the fields of thermal management and electrical enclosure.

A novel ammonium salt type polymeric antistatic agent (PDSH) was synthesized from methacrylatoethyl trimethyl ammonium chloride, styrene, and 2-hydroxyethyl methacrylate via radical polymerization. Antistatic poly(acrylonitrile- co -butadiene- co -styrene) (ABS)/PDSH composites were prepared by blending PDSH with ABS resin. The results showed that the surface resistivity of ABS/PDSH composites with PDSH addition decreased significantly. The surface resistivity of ABS/PDSH composites containing 20 wt% PDSH was around 10 9 –10 10 Ω, which was about 10 6 times lower than that of neat ABS. At the same time, ABS/PDSH composites had good thermal stability and hydrophilicity. The PDSH was more uniformly dispersed within the ABS resin and had less influence on the mechanical properties of the composites. With the demonstrated properties, the prepared copolymer PDSH can serve as a well-integrated antistatic agent and display potential for the antistatic treatment of ABS.

Lignin-based flame retardants represent great promising next-generation flame retardants due to their sustainability, unique aromatic structure, and high charring capability. However, their applications are still limited by the compatibility, processability, and efficiency of flame retardancy. Here, a green functional lignin-based nanofiller (lignin-diethylenetriamine/red phosphorus nanoparticles, Lignin-N-P NPs) was prepared by the chemical modification and co-precipitation. After blending with the commercial acrylonitrile butadiene styrene copolymers (ABS), the physical, chemical, and flame retardant properties of the blends reveal that Lignin-N-P NPs/ABS blend has acceptable processability, mechanical properties, and significantly improved thermal stability and fire performance. Its values of peak heat release rate and total heat released per unit area were significantly dropped 67.8% and 77.5%, respectively. This study will initiate a new design for not only flame retardants but also lignin-based materials.

The increasing amount of e-waste plastics needs to be disposed of properly, and removing the brominated flame retardants contained in them can effectively reduce their negative impact on the environment. In the present work, TBBPA-bis-(2,3-dibromopropyl ether) (TBBPA-DBP), a novel brominated flame retardant, was extracted by ultrasonic-assisted solvothermal extraction process. Response Surface Methodology (RSM) achieved by machine learning (support vector regression, SVR) was employed to estimate the optimum extraction conditions (extraction time, extraction temperature, liquid to solid ratio) in methanol or ethanol solvent. The predicted optimum conditions of TBBPA-DBP were 96 min, 131 mL g −1 , 65 °C, in MeOH, and 120 min, 152 mL g −1 , 67 °C in EtOH. And the validity of predicted conditions was verified.

Coal gasification fine slag glass beads (CGFSGBs) were processed via an efficient pneumatic separation technique. CGFSGB products (CGFSGB-S1, CGFSGB-S2, and CGFSGB-S3) with different sizes were acquired. The heavy calcium carbonate (CaCO 3 ) was used as comparative filler. Effects of particle size and geometric shape on mechanical strengths, flow properties, and solid density of filled acrylonitrile–butadiene–styrene (ABS) were investigated. The mechanical strengths of composites decreased with increasing CGFSGB weight fraction, while MFR and solid density increased. The mechanical strengths were found to increase with decreasing CGFSGB size, and spherical surface of the CGFSGB is more beneficial to improve interface adhesion strength than square surface of the CaCO 3 . The flow property analysis showed that the ABS/CaCO 3 composites have better fluidity and the advantages in the processing energy consumption. However, the incorporation of CaCO 3 resulted in the higher solid-state density. In summary, CGFSGBs have the potential to replace CaCO 3 in the ABS market. © 2020 Wiley Periodicals, Inc. J. Appl.

To mitigate the fire hazard associated with acrylonitrile butadiene styrene (ABS), cerium molybdate (Ce 2 (MoO 4 ) 3 , CM) nanosheets were synthesized via a hydrothermal method and subsequently incorporated into ABS (ABS/CM). The obtained ABS/CM composites exhibited significantly enhanced flame retardancy and smoke suppression. At a 15 wt% CM loading, the peak heat release rate (PHRR) and peak smoke production rate (PSPR) decreased by 39.4 % and 40.5 %, respectively, while the ignition time increased by 26 s compared to pristine ABS. Concurrently, the tensile strength increased by 12.8 %, although the elongation at break decreased by 48.2 %. Thermal stability was also improved, with the residual char yield at 600 °C rising dramatically from 0.89 wt% for pristine ABS to 15.97 wt% for the ABS/CM15. Mechanistic analysis revealed that the CM nanosheets migrate to the composite surface during combustion, forming a protective cerium/molybdenum-rich char layer. This layer acts as an effective heat and oxygen barrier through condensed-phase action. This work demonstrates CM as an efficient halogen-free multifunctional additive for enhancing the fire safety of ABS composites.

Photocatalysis is widely acknowledged as an efficient and environmentally friendly method for treating dye-contaminated wastewater. However, the utilization of powdered photocatalysts presents significant challenges, including issues related to recyclability and the potential for secondary pollution. Herein, a novel technique based on 3D printing for the synthesizing of iron oxide (Fe2O3) involving chlorella was presented. Initially, chlorella powders were immobilized within acrylonitrile butadiene styrene (ABS) and thermoplastic polyurethane (TPU) substrate plastics using melt extrusion technology. Subsequently, these composite materials were transformed into ABS/TPU/chlorella skeletons (ATCh40), through fused deposition molding (FDM) technology. The integration of Fe2O3 onto the ATCh40 (ATCh40-Fe2O3) skeletons was accomplished by subjecting them to controlled heating in an oil bath. A comprehensive characterization of the synthesized materials confirms the successful growth of Fe2O3 on the surface of 3D skeletons. This strategy effectively addresses the immobilization challenges associated with powdered photocatalysts. In photocatalytic degradation experiments targeting methyl orange (MO), the ATCh40-Fe2O3 skeletons exhibited a remarkable MO removal rate of 91% within 240 min. Under conditions where the pH of MO solution was maintained at 3, and the ATCh40-Fe2O3 skeletons were subjected to a heat treatment in a 150 °C blast drying oven for 2 hours, the degradation rate of MO remained substantial, achieving 90% removal after 6 cycles. In contrast, when the same synthetic procedure was applied to ABS/TPU (AT) skeletons, the resulting product was identified as α-FeOOH. The MO removal rate by the AT-α-FeOOH skeletons was considerably lower, reaching only 49% after 240 min. This research provided a practical approach for the construction of photocatalytic devices through the use of 3D printing technology.

Interlayer bonding strength (IBS) is the decisive factor governing the performance of fused deposition modeling (FDM) parts. However, limited research has been conducted on regulating the material molecular structure within FDM processes to enhance IBS. In this study, different acrylonitrile butadiene styrene (ABS) specimens for FDM were fabricated by strategically modifying the molecular structure of ABS through emulsion grafting polymerization (to control grafted layer thickness) and seed amplification methodology (to achieve a bimodal particle size distribution). The grafted layer thickness of ABS polybutadiene (PB) phase particles, the compatibility between the two phases, the IBS, and the resulting properties of the FDM parts were investigated. The results demonstrate that increasing the grafted layer thickness of the ABS PB phase particles enhances the compatibility between the phases and increases the fluidity of the ABS melt. Consequently, this improves both the diffusion ability and time for molecular chains during the FDM process, thereby further enhancing IBS. Regulating a bimodal distribution of PB phase particle size further increased ABS melt fluidity, leading to additional IBS improvement. The IBS was directly quantified by T-peel tests, revealing an 110.8 % increase from ABS-1 to ABS-3, with ABS-3 exhibiting a 32.2 % higher peel strength (3.12 N/mm) than a commercial ABS. Following IBS enhancement, the impact strength increased by 60.7 % at 25 °C and by 161.5 % at −30 °C, while the tensile strength increased by 55.6 %. The retention rate of low-temperature impact strength increased by 62.6 %. Furthermore, the dimensional stability of the FDM parts demonstrated significant improvement.

The work reports a novel strategy for combining polymers and metal–organic frameworks (MOFs) into composites for adsorption applications. Calcium silicate (CaSiO3) was introduced into acrylonitrile butadiene styrene/thermoplastic polyurethane (ABS/TPU) alloy, and the CaSiO3/ABS/TPU skeleton was fabricated by 3D printing technology. The Ca-MOF was directly loaded on the surface of acetone-etched 3D skeleton by in-situ growth method. The obtained 3D skeleton was characterized and the performance of methylene blue (MB) adsorption was determined. It is clear that Ca-MOF is successfully loaded on the surface of 3D skeleton due to the presence of CaSiO3. The MB adsorption ratios of the solutions with initial concentrations of 50, 100 and 200 mg/L at the equilibrium time (5 h) are 88%, 88% and 80%, respectively, revealing good MB adsorption performance of the 3D skeleton. The MB adsorption ratio remains 70% at six runs of adsorption–desorption experiment, indicating the excellent recovering property of the skeleton. The results show that the prepared CaSiO3/ABS/TPU 3D skeleton is a candidate adsorbent for printing and dyeing effluent treatment.Keywords:3D printing;metal–organic framework;in-situ growth;adsorption;methylene blue

It is an intractable challenge that the hierarchical MXene-based nanohybrid fillers are intended to modify the inherent flammability and easily breeding bacteria property of ABS polymeric materials, thereby facilitating wide applicability of ABS composites. Here, an interface engineering strategy was proposed, wherein polyethyleneimine (PEI)-modified silver nanocubes (AgNCs) was firmly assembled on MXenes via electrostatic interaction to construct 0D–2D hierarchical MXene-based nanohybrids (MXene@PEI@AgNC). The MXene was protected and the interface compatibility between MXene-based nanohybrid and ABS matrix was enhanced. Results revealed that the unique hierarchical structure of the composite promoted enhanced dispersion of MXene@PEI@AgNC in the ABS matrix. Combustion tests showed that 1.0 wt%MXene@PEI@AgNC provided the ABS with effective fire safety. Moreover, ABS-1.0 wt%MXene@PEI@AgNC exhibited a 31.88 % decrease in peak heat release rate, a 39.60 % decrease in peak smoke release rate, a 41.50 % decrease in peak CO 2 production rate, and a 50.04 % reduction in the smoke factor. Meanwhile, 1.0 wt%MXene@PEI@AgNC improved the tensile strength of ABS-1.0 %MXene@PEI@AgNC (+18.1 %) without reducing the elongation at break. They also enhanced the antibacterial properties of ABS-1.0 %MXene@PEI@AgNC. This study proposed a novel and feasible approach to address the interfacial stability of MXene and to construct MXene-based hierarchical nanoblends, thereby facilitating the wide practical applications of polymeric nanomaterials in industry.

Acrylonitrile-butadiene-styrene (ABS) is widely used but inherently flammable, and conventional flame retardants often suffer from poor compatibility, high migration tendency, or compromised mechanical properties. Herein, a novel nitrogen-phosphorus (N/P) synergistic flame retardant, ammonium 1,3,5-triazine-2,4,6-triyl tri(phosphate) (ATTP), was synthesized, and a nanoscale core-shell flame retardant (NCSFR) with ATTP as the core and crosslinked polyacrylates as the shell was constructed via a supramolecular lock-shell strategy. This unique supramolecular encapsulation not only transforms micron-sized rod-like ATTP into 300–900 nm nanoparticles but also enhances interfacial affinity with ABS. At 40 wt% loading, NCSFR/ABS achieved a limiting oxygen index (LOI) of 24.8% (vs. 17.1% for pure ABS) and superior combustion inhibition (peak heat release rate reduced by 46.2% vs. pure ABS), outperforming ATTP/ABS. TG-IR and SEM confirmed a N/P synergistic biphasic mechanism, that is, gas-phase release of non-flammable gases and phosphorus radicals, and condensed-phase formation of a dense char layer. Benefiting from the supramolecular lock-shell structure, NCSFR/ABS exhibited better mechanical properties than ATTP/ABS at the same 40 wt% loading (tensile strength: 25.3 MPa vs. 21.9 MPa), excellent high-temperature aging resistance (96.77% LOI retention after 100 ℃/2 h aging), and migration resistance (13.33% mass loss after 80 ℃ water immersion, versus 40% for ATTP/ABS). This work highlights the superiority of supramolecular encapsulation in balancing flame retardancy, mechanical performance, and durability for ABS, addressing key bottlenecks of traditional additives.
