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. Due to superior electrical insulation, good processability, light weight, and low cost, polymers have been widely used in electrical and electronic fields.1 However, the thermal conductivity of typical polymer is far below the demand for heat dissipation. In recent years, some non-covalent methods are explored, which are usually applying physical interaction between the matrix and the fillers such as Van der Waals attractions, electrostatic interactions, π-effects, and hydrogen bonding. [38][39][40][41][42] Compared with covalent methods, non-covalent modification is much more convenient, and it can keep the intrinsic properties of BN away from disruption of extended π-conjugation systems.In this study, BN platelets were functionalized by a non-covalent method with dopamine (DOPA) as a modifier. The poly(DOPA) layer indeed played an important role in enhancing the interfacial interactions between the fillers and the matrix. The thermal conductivity and other properties of ABS/BN composites were discussed. | Surface modification of BNThe poly(DOPA) coated BN (donated as mBN) was prepared in a typical route as follows: 2-g BN was mechanically stirred and sonicated for 2 hours in a 200-mL flask containing a phosphate (Na 2 HPO 4 + KH 2 PO 4 ) buffer solution (PBS, pH 8.5). The pH value was determined by pH meter (PHS-25, Shanghai Scientific Instrument Co., Ltd., China). Then, 0.2-g DOPA was charged into the resulting mixture, followed by vigorously stirring at 28°C for the fixed periods (t = 1, 2, 5, 10, 20 hours) to ensure self-polymerization on the surface of BN platelets. Subsequently, the suspension was filtered through a 0.45-μm membrane and washed several times with deionized water until the filtrate became colorless and neutral to get the modified BN platelets (mBN).The final product was dried in a vacuum oven at 40°C for 24 hours. Figure 1 describes the possible mechanism referred to in some literatures. 43,46 Th...

Objectives: The present study examines the effect of Calcium Sulphate (CaSO 4 ) microparticles as filler materials and ABS as matrix materials on mechanical properties and wear performance of composite materials, which are injected into molds for preparation of the specimens. Methods: The CaSO 4 microparticles are added at different weight fractions to the acrylonitrile butadiene styrene (ABS) polymer composites. Moreover, the reinforcement has improved tensile strength, wear properties, and hardness. Wear behavior was measured on ABS/ CaSO 4 by a wear monitor (ASTM G99) and pin-ondisc type friction. As part of this experiment, the cutting speed, loading, and sliding distance of composite materials are considered and optimized for their properties. To observe and analyze the characteristics of this material, tensile strength and wear tests were conducted. By analyzing SEM images, we were able to study the fractured material's morphology. In this study, an orthogonal array (L 9 ) and control parameters were used to examine wear debris that explored the flacks and grooves of the content. Findings: An increase in toughness and modulus of resilience (due to an increase in filler content) and the contribution of normal load to wear rate (37.44%) constitute the most important contribution to work. Novelty : we have evaluated the various tribological and mechanical properties of polymer composite specimens using the Taguchi method.

Simultaneous Enhancement of Photocatalytic Bactericidal Activity and Strength Properties of Acrylonitrile-Butadiene-Styrene Plastic Via a Facile Preparation with Silane/TiO2

This work aims to enhance the photocatalytic antibacterial performance of plastics according to the JIS Z 2801:2010 standard, and to determine their mechanical properties by studying: (i) the influence of calcination on titanium dioxide (TiO2); (ii) modification with different TiO2 concentrations, and; (iii) the effect of silane as a coupling agent. Acrylonitrile-butadiene-styrene plastics (ABS) and Escherichia coli (E. coli) were chosen as the model plastic and bacteria, respectively. The 500 °C calcined TiO2 successfully provided the best photoantibacterial activity, with an approximately 62% decrease of E. coli colony counts following 30 min of exposure. Heat treatment improved the crystallinity of anatase TiO2, resulting in low electron-hole recombination, while effectively adsorbing reactants on the surface. ABS with 500 °C-calcined TiO2 at the concentration of 1 wt % gave rise to the highest performance due to the improved distribution of TiO2. At this point, blending silane coupling agent could further improve the efficacy of photoantibacterial activity up to 75% due to greater interactions with the polymer matrix. Moreover, it could promote a 1.6-fold increase of yield strength via increased adherent bonding between TiO2 and the ABS matrix. Excellent photocatalytic and material stability can be achieved, with constant photocatalytic efficiency remaining for up to five reuse cycles without loss in the yield strength.
