甘蔗渣微晶纤维素增强聚乳酸复合膜的性能
Properties of Bagasse Cellulose Microcrystal Reinforcing Poly Lactic Acid Composites
摘 要
利用酸碱结合的方法提取出甘蔗渣纤维素, 经酸水解制备甘蔗渣微晶纤维素(BCMC); 以BCMC为增强材料, 以生物可降解材料聚乳酸(PLA)作为基体, 制备了BCMC/PLA复合膜, 并对复合膜的结构、热稳定性和力学性能进行了研究。结果表明: BCMC均匀地分散于PLA基体中, 没有发生明显的团聚现象; BCMC的加入增大了复合膜的结晶度; 当BCMC的质量分数为5%时增强效果最佳, 与纯的PLA膜相比, 复合膜的起始分解温度提高了30.73 ℃, 拉伸强度提高了50.98%, 断裂伸长率提高了16.25%。

Abstract
Bagasse cellulose extracted by method of combination of acid and alkali hydrolyzed to yield bagasse cellulose microcrystal (BCMC) using acid hydrolysis. The biodegradable composite films were prepared by using the bagasse cellulose microcrystal as filler and poly lactic acid (PLA) as the polymeric matrix. The structure, the mechanical properties and the thermal stability of the composite film were tested. The results show that the BCMC distributed well in the PLA matrix without obvious aggregation, adding the degree of crystallization of composite films. When the mass fraction of BCMC was 5%, the optimized integrated performance of composite films could be gained. The initial decomposition temperature increased 30.73 ℃, the tensile strength increased by 50.98% and the elongation at break increased by 16.25% compared with those of the pure PLA.
