Mussel-inspired reinforcement of a biodegradable aliphatic polyester with bamboo fibers

Abstract Natural fiber-reinforced biocomposites displaying light weight, low thermal conductivity and reduced environmental footprint are increasingly relevant in structural, packaging, cementitious masonry materials. However, the poor interfacial compatibility between fibers typical polymers has limited development of mechanical strength water resistance. Here, we report a green, facile effective method inspired by nature to promote adhesion based on biodegradable aliphatic polyester (polybutylene succinate, PBS). For this purpose, PBS was reinforced with bamboo modified (3-aminopropyl) triethoxysilane polydopamine (PDA). The PDA deposition covalent were promoted self-polymerization Michael addition and/or Schiff secondary reactions. A distinct improvement reinforcement achieved together gains performance, including tensile (70%), modulus (25%), flexural (37%), (24%) impact (63%). results far exceeded those measured for other while simultaneously introduced
