摘　　要：以微晶纤维素为填充剂,聚乳酸为基体,采用熔融共混法制备PLA/MCC生物降解复合材料。考察了聚甲基丙烯酸甲酯(PMMA)表面处理的微晶纤维素对复合材料性能的影响。结果表明,PMMA包覆MCC增加了弯曲强度。表面改性处理提高了MCC的热稳定性,使其加工温度提高了。The biodegradable composites were prepared with microcrystalline cellulose （MCC） as filler and polylactic acid （PLA） as polymer matrix by melt blending. The effect of PMMA surface treated MMC on the performance of composite was investigated. The results showed that the PMMA cladding could improve the flexural strength of MCC. The surface modification could improve the thermal stability of MCC and enhance the processing temperature of composites.
