| 摘 要： | 采用玉米秸秆微晶纤维素(CSCMC)作为增强剂,生物可降解材料聚乙烯醇(PVA)作为基体,制备了PVA/CSCMC复合膜材料,并对复合膜的结构、热稳定性能、力学性能进行了测试。结果表明,玉米秸秆微晶纤维素可增强复合膜材料的热稳定性能和力学性能。当CSCMC的质量分数为10%时增强效果最佳,与纯的PVA膜相比,复合膜的起始分解温度和最大重量损失率温度分别提高了19.25℃和17.17℃,拉伸强度提高了37.91%,断裂伸长率提高了58.93%。

| Abstract: | The biodegradable composite films were prepared from corn stalks cellulose microcrystal(CSCMC) as the filler and poly(vinyl alcohol)(PVA) as the polymeric matrix.The crystallinity,the tensile properties and thermal properties of film were tested.The results showed that the tensile properties and the thermal properties of the PVA∕CSCMC composite were improved by the addition of corn stalks cellulose microcrystal.When the mass fraction of CSCMC was 10%,the initial decomposition temperature and maximum weight loss rate of film were raised by 19.25℃ and 17.17℃,the tensile strength increased by 37.91%,and the elongation at break increased by 58.93% compared to those of pure PVA. |
