摘要

The aim of this work was to enhance the performance of a wood pulp/polylactic acid (PLA) biocomposite using epoxidized natural rubber (ENR)-grafted-modified microfibrillated cellulose (MFC) as a novel compatibilizer. MFC was modified by two different methods of silanization:one with 3-(trimethoxysilyl) propyl methacrylate and the other with 3-aminopropyl-triethoxyl silane. The two types of modified MFC were grafted onto ENR via a solution-casting method. Compared with the uncompatibilized biocomposite, the flexural strength and impact resistance of the biocomposite compatibilized with ENR-amino silanized MFC were increased by 168 and 261, respectively. SEM images and DMTA analysis confirmed the compatibility among the three phases of pulp, PLA, and ENR. Meanwhile, the use of ENR-methacrylate silanized MFC as a compatibilizer in the biocomposite also demonstrated the improvement of compatibility compared with non-MFC and MFC systems. The durability of the biocomposites was assessed in an accelerated weathering test. The pulp/PLA/ ENR-methacrylate silanized MFC showed the lowest degradation rate, due to the methacrylate group of silane acted as a chromophore to mitigate UV absorption.
