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...

There has been a growing interest in utilizing fibers as reinforcement to produce composite materials. Scientists prefer thermoplastic polymeric matrices than thermosets due to the low production cycle, lower cost of processing and high reparability of thermoplastics. Fiber-reinforced thermoplastic matrix composites have gained commercial success in the semistructural and structural applications. Various fibers are widely used as reinforcement in thermoplastic polypropylene (PP) matrix to prepare composites. Mechanical properties of fiber-reinforced PP composites (FRPCs) are studied by many researchers and few of them are discussed in this article. Various fiber treatments, which are carried out to improve the fiber–matrix adhesion to get improved mechanical properties, are also discussed in this article. This article also focuses on coupling agents and fiber loading which affect the mechanical properties of FRPCs significantly.

“…The waste silk fabrics from a local silk manufacturer were collected for the purpose of reinforcement. In an earlier study [9], it was proven that the blend containing 4 wt% of acrylonitrile-butadiene-styrene (ABS) in epoxy (which is used as a matrix for the preparation of the composites in the current study) was shown to have better properties when compared to the other combinations of the blend prepared with 2, 6, 8, and 10 wt% of ABS in epoxy.…”

Epoxy is toughened with acrylonitrile-butadiene-styrene copolymer and composites are developed using varying weight fractions of waste silk fabric as reinforcement. Properties, such as density, void content, and weight reduction of the composites developed are studied and compared to that of pure epoxy/silk fabric composites. A chemical resistance test of these toughened resin composites is also carried out. This revealed that toughening the matrix used for composites enhances the resistance of the composites.
