摘要

The poor compatibility between the surfaces of bamboo fiber (BF) and polylactic acid (PLA) has an adverse impact on the properties of their composites. This study utilized an environmentally-friendly synergistic treatment to fabricate a polydopamine (PDA) functional coating on the surface of the BF. This coating acted as a bridge to introduce an epoxy functional group layer through the silane coupling agent KH560. Characterization experiments verified the successful grafting of KH560 onto the fibers. Subsequently, the modified bamboo fiber was compounded with polylactic acid (PLA) and polybutylene adipate-co-terephthalate (PBAT), which served as an auxiliary additive, to prepare bamboo-plastic composites via melt blending and hot pressing. The modified composites demonstrated a significant enhancement in mechanical properties. Specifically, the flexural strength increased by 63%, and the tensile strength increased by 48.41%. Additionally, the flexural modulus and tensile modulus increased by 70.57 and 54.17%, respectively. Furthermore, the incorporation of modified bamboo fibers enhanced the thermal stability and water resistance of the PLA/PBAT composites. These composites, which have undergone synergistic treatment, possess extensive application potential in the field of biocomposites.
