摘要
在前期热塑性塑料原位成纤研究的基础上，尝试利用原位成纤方法制备炭黑(CB)／聚对苯二甲酸乙二醇酯(PET)／高密度聚乙烯(HDPE)原位导电微纤网络复合材料(CEMN)，以期增强复合体系的力学强度。通过对CEMN体系与CB／PE体系的力学性能测试发现，CEMN体系的拉伸强度低于普通CB／PE复合物。为增强复合体系的力学性能，应改变加工过程及降低体系中CB的用量。
Based on the study of in-situ fibrillation of general engineering plastics/general-purpose plastics, carbon black (CB)/poly(ethylene terephthalate) (PET)/high density polyethylene (HDPE) composites with in-situ electrical conductive microfibril network (CEMN) were prepared by extrusion-hot stretching-quenching. For comparison purpose, common CB/PE composite was also prepared by the same method. Testing the mechanical properties of CEMN and common CB/PE composite indicated that the tensile strength of CEMN was even lower than that of the common CB/PE composite. The possible reason causing poor mechanical properties of CEMN was discussed and some useful measures to improve the mechanical properties of CEMN were proposed in the future work..
