采用玉米秸秆微晶纤维素（CSCMC）作为增强材料,生物可降解材料聚乳酸（PLA）作为基体,制备了CSCMC/PLA复合膜材料,并对复合膜的结晶度、热稳定性能、力学性能进行了测试。结果表明,复合膜材料的热稳定性能和力学性能优于纯聚乳酸膜。当CSCMC的质量分数为10%时,复合膜的热稳定性能和力学性能达到最佳,与纯PLA膜相比,起始分解温度提高了34.38℃,拉伸强度提高了58.3%,断裂伸长率提高了31.1%。
The biodegradable composite films were prepared from corn stalks cellulose microcrystal（CSCMC） as the filler and poly（lactic acid）（PLA） as the polymeric matrix.The crystallinity,the tensile properties and the thermal properties of the composite flim were tested.The results show that the tensile properties and the thermal properties of the CSCMC/PLA composite were improved by the addition of corn stalks cellulose microcrystal.When the mass fraction of CSCMC is 10%,the initial decomposition temperature increases by 34.38℃,the tensile strength increases by 58.3% and the elongation at break increases by 31.1% compared to that of the pure PLA.
