| 摘 要： | 采用固相剪切碾磨方法成功制备了聚氯乙烯(PVC)-高岭土复合粉体,实现了高岭土的片层剥离和在PVC基体中的纳米分散及对PVC的同步增强增韧。通过X射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)表征了PVC-高岭土纳米复合材料的结构,研究了其力学性能。结果表明,30次碾磨,高岭土的特征衍射峰几乎消失,高岭土以约30 nm片层厚度均匀分散于PVC基体,径厚比超过10。与简单填充复合方法相比,固相剪切碾磨技术制备的PVC/高岭土纳米复合材料的力学性能有较大提高。在高岭土质量分数为4%时,断裂伸长率由87.3%提高到274.6%,提高了214.7%;拉伸强度由47.7 MPa提高到54.0 MPa。
