以甘蔗渣微晶纤维素(BCMC)作为增强材料,聚乙烯醇(PVA)作为基体,制备了BCMC/PVA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,甘蔗渣微晶纤维素增强复合膜材料的热稳定性能和力学性能。当BCMC的质量分数为5%时增强效果最佳,与纯PVA膜相比,起始分解温度和最大重量损失率温度分别增加了11.71℃和36.86℃,拉伸强度提高了17.52%,断裂伸长率提高了29.58%。
BCMC / PVA composite membrane materials were prepared with bagasse microcrystalline cellulose (BCMC) as reinforcing material and polyvinyl alcohol (PVA) as matrix, and the structure, thermal stability and mechanical properties of the composite membranes were tested. The results showed that bagasse microcrystalline cellulose enhanced the thermal stability and mechanical properties of composite membrane materials. When the mass fraction of BCMC is 5%, the enhancement effect is the best. Compared with pure PVA film, the initial decomposition temperature and the maximum weight loss rate increase by 11.71 ℃ and 36.86 ℃ respectively, the tensile strength increases by 17.52% The length increased by 29.58%.
