摘要: 通过熔融混炼法制备了聚氯乙烯(PVC)/埃洛石纳米管(HNTs)复合材料,通过力学性能测试和扫描电子显微镜、透射电子显微镜等方法研究了HNTs含量对复合材料形貌与性能的影响,并分析了HNTs的作用机理。结果表明,HNTs可以对PVC产生增强增韧的作用;PVC/HNTs复合材料的储能模量和玻璃化转变温度相对纯PVC均有所增加;不同含量的HNTs在PVC基体中的分散性均较好且无大面积团聚的现象;HNTs与PVC间具有较强的界面作用力,其界面作用半经验参数(B)值为4.35。

Abstract: Composites based on poly(vinyl chloride) (PVC) and halloysite nanotubes (HNTs) were prepared by a melt mixing method. Effect of HNTs content on morphologies and properties of composites was investigated by mechanical measurements, scanning electron microscopy and transmission electron microscopy, and effecting mechanism of HNTs toward PVC was analyzed. The results indicated that HNTs could generate a toughening effect on PVC, and PVC/HNTs composites exhibited an increase in storage modulus and glass transition temperature in comparison pure PVC. HNTs presented a good dispersibility in PVC matrix, and there was no agglomeration of HNTs observed with a variation of content of HNTs, which may be attributed to a good interfacial adhesion between PVC and HNTs according to an interface semiempirical parameters B of 4.35.
