摘要 采用固相法,对粘土进行有机插层改性;并与聚氯乙烯(PVC)熔融插层制备了纳米复合材料。结果表明,偶联剂KH560处理的有机粘土(用Org-560表示)与PVC形成PVC/org-550插层型纳米复合材料,而偶联剂KH550处理的有机粘土(用Org-550表示)与PVC形成的PVC/Org-550则是剥离型纳米复合材料;PVC/有机牯土纳米复合材料的玻璃化转变温度高于PVC;Org-550对PVC的力学性能优于Org-560的。 The organic-clay was treated with swelling agent and silane coupling agent by solid state method, and the poly(vinyl-chloride) (PVC)/organic-clay nanocomposites were prepared by melt intercalation. The reults show that the PVC/org-550 nanocomposites, which is treated by silane coupling agent KH-550, possesses exfoliation structure. The PVC/org-560 nanocomposites, which is treated by KH560, possesses intercalation structure. The glass transition temperature(Tg) of PVC/ organic-clay nanocomposites is higher than that of PVC. The mechanical properties of the PVC/org-550 nanocomposites are better than those of PVC/org-560 nanocomposites.
