摘要
采用熔融插层法制备了聚氯乙烯(PVC) /蒙脱土(MMT)纳米复合材料并进行了表征,研究了PVC/MMT纳米复合材料的力学性能。结果表明:PVC进入到有机MMT的片层间形成了纳米复合材料,但PVC不能进入钠基MMT的片层间,形成纳米复合材料;蒙脱土的加入提高了PVC的力学性能,而且PVC/有机MMT纳米复合材料的拉伸和冲击强度总是优于PVC/钠基MMT复合材料;对PVC/有机MMT纳米复合材料而言,复合材料的V型缺口冲击比U型缺口冲击敏感,其力学性能随热处理时间延长而降低,但PVC/有机MMT复合材料比PVC/钠基MMT的抗热性好。
Polyvinyl Chloride (PVC)/montmorillonite(MMT) nano-meter composites were prepared by means of melt intercalation, the prepared composites were characterized, and the mechanical properties of the composites were studied. The results of X-ray diffraction(XRD) and FTIR indicated that PVC/Org-MMT was nano-meter composite, and the composites had good mechanical properties.
