| 摘 要： | 采用溶液共沉淀法制备了定向碳纳米管/氯化聚乙烯复合材料,研究了定向碳纳米管预处理方法和其用量对复合材料力学性能的影响,并利用扫描电子显微镜(SEM)观察了复合材料拉伸断面的形貌特征。结果表明:定向碳纳米管/氯化聚乙烯复合材料的拉伸强度随定向碳纳米管加入量的增加而增大,当定向碳纳米管的加入量为5份(氯化聚乙烯为100份)时,其拉伸强度最大,与纯氯化聚乙烯的拉伸强度相比,提高了75%;化学修饰后的定向碳纳米管在氯化聚乙烯基体中有了较好的分散性及较强的界面结合力。

| Abstract: | Aggregation of carbon nanotubes(CNTs) leads to a difficult dispersion of CNTs in polymer.In order to solve this problem,the surface of CNTs was modified in the way in which the aligned carbon nanotubes(ACNTs) was sidewall functionalized through electrophilic addition reaction.And the products were characterized by IR spectra.ACNTs/CPE composites were prepared by the method of solution co-precipitation.After tensile measurement,it was found that the tensile strength of the composites could enhance 75%.The fracture surface of the composites were characterized by SEM,the results showed that a homogeneous dispersion of ACNTs throughout CPE matrix and a strong interconnection between ACNTs and the matrix have been successfully gained. |
