摘要
以聚丙撑碳酸酯(PPC)和壳聚糖(CS)为主要原料,在其他添加剂的作用下制备可生物降解性塑料聚丙撑碳酸酯/壳聚糖共混物,通过加入不同量的壳聚糖来研究壳聚糖对共混物的力学性能和微观形态的影响。结果表明:共混物熔体流动速率在CS为5份时有最大值,共混物的加工流动性得到提高,而当CS为10份时共混物断裂伸长率有最大值,所以加入CS及其他助剂使共混物的力学性能得到显著提高,共混物的韧性和加工性能得到提高。
Biodegradable material,the PPC/CS blend was prepared from polypropylene carbonate and chitosan by adding some additives.Influence of chitosan dosage on mechanical properties and microstructure of the blend was studied.The results show that when PPC:CS is 100:5,the melt flow rate of the blend is maximum,processing liquidity of the blend is high;when PPC:CS is 100:10,elongation of the blend is maximum,and the addition of CS and other additives has dramatically improved mechanics properties of the blend,toughness and processing properties of the blend has also been improved.
