摘　　要：采用溶液共混的方法制备了活性白土/聚碳酸亚丙酯(PPC)复合材料,研究了活性白土的含量对所得复合材料结构、热性能和力学性能的影响。研究结果表明低含量的活性白土在PPC基体中具有较好的分散性,且两者之间具有较好的界面作用;活性白土的引入有效地提高了PPC的玻璃化转变温度(T_(g))和力学强度,同时也可以在一定程度上提高PPC的热稳定性。Activated clay(AC)/poly(propylene carbonate)(PPC)composites were prepared by solution mixing method.The effect of AC content on the structure,thermal and mechanical properties was investigated.The results show that AC with low content can be uniformly dispersed in PPC matrix,and good interfacial interaction exists between them.The introduction of AC into PPC matrix can effectively improve its glass transition temperature and tensile strength.At the same time,the thermal stability of PPC can certainly be improved by AC.These results indicate that AC is an efficient modifier to improve the properties of PPC.
