摘　　要：将细菌纤维素(BC)作为增强材料加入聚碳酸亚丙酯(PPC)基体中,采用溶液浇铸法制备了PPC/BC复合薄膜材料,研究了BC用量对PPC拉伸性能、热稳定性能及降解性能的影响。结果表明:随着BC用量的增加,PPC/BC复合薄膜的拉伸强度和热稳定性能明显提高,降解速率减慢。Taking bacterial cellulose （BC） as reinforcement and polypropylene carbonate （PPC） as matrix, PPC/BC composite film was prepared by solvent casting. The effect of BC content on tensile property, thermal stability and degradability of PPC was studied. The results show that with the increase of BC content, the tensile strength and thermal stability of PPC/BC composite film are improved obviously, but the degradation rate is reduced.
