Abstract

An adherent polymer film based on a composite of polyacrylonitrile/multiwall carbon nanotubes (PAN/MWNTs) have been elaborated on a copper substrate. The first layer is an electrografted PAN brush on which of a subsequent layer of PAN/carbon nanotubes composite has been deposited by simple dipping from solution in dimethylformamide (DMF). MWNTs have been previously chemically functionalized with 3-cyanopropyltrichlorosilane to promote de-bundling and homogeneous dispersion of the carbon nanotubes in the composite.

摘要

基于聚丙烯腈/多壁碳纳米管（PAN/MWNTs）复合材料的附着聚合物膜已在铜基板上制备。第一层是电接枝的PAN刷，随后通过从二甲基甲酰胺（DMF）溶液中简单浸渍在其上沉积一层PAN/碳纳米管复合材料。MWNTs先前已用3-氰基丙基三氯硅烷进行化学功能化，以促进碳纳米管在复合材料中的解束和均匀分散。
