摘要：

Bacterial cellulose nanofiber-reinforced unsaturated polyester resin composites (BC/UPR) were prepared using vinyl-triethoxy silane coupling modified BC fibres by the method of resin transfer molding (RTM) and subjected to mechanical tests in order to study the effect of surface treatment on the properties of composites. The results show that coupling treatment did not change the morphology of BC nanofibers, while it changed the chemical states of the BC fiber's surface. The XPS result indicates that chemical bonding was formed at the interface between UPR matrix and BC fibers after surface treatment, which enhanced the mechanical properties of composites. After treatment, tensile strength, flexure strength, shear strength and tensile modulus of the composites with a fiber volume fraction (V-f) of 10% were increased by 117.7%, 38.4%, 38.7% and 27.6%, respectively.
