摘　　要：综述了目前聚合物/碳纳米管(CNTs)复合材料在导电方面的研究现状,从CNTs在聚合物基体中的分散状况、复合材料的制备方法(熔融共混法、溶液混合法以及原位聚合法)、CNTs的排列有序程度(外加磁场法和外加电场法)、CNTs的长径比等因素出发,对复合材料在导电性能方面的最新进展进行了系统阐述。另外,还指出提高CNTs在聚合物中的分散状况是提高复合材料导电性能的发展方向。This paper reviewed the recent advances in the electrical property of polymer/carbon nanotube（CNT） composites. CNTs could enhance polymer matrix＇s electrical property because of its high electrical conductivity. However, CNTs were extremely difficult to disperse in a polymer matrix and usually intend to agglomerate to form stabilized bundles. The main challenge in the preparation of CNT-reinforced composites was to find a way to make CNTs homogeneously dispersed in polymer matrix. So far, there were several methods for the dispersion of carbon nanobubes, such as solution mixing, in-situ polymerization, melt mixing and chemical functionalization of the carbon nanotubes, etc. Numerous studies showed that the percolation threshold and conductivity depend strongly on the polymer type and fabrication method, aspect ratio of CNTs, uniform spatial distribution of individual CNTs and degree of alignment. These influencing factors and preparation of high performance polymer/CNTs composites were described in this review. Moreover, both the current challenge and the future development towards the field of polymer/CNTs electrical conductive composites were also discussed in this article.
