导电高聚物聚2，5－二甲基苯胺的化学合成与特性

Synthesis and Characteristics of Poly(2,5-dimethylaniline) as Conductive Polymer

报道了聚２，５－二甲基苯胺（ＰＤＭｅＡｎ）的化学合成，并用标准四探针方法测定其电导率，以ＦＴＩＲ、ＵＶ－Ｖｉｓ吸收光谱、元素分析和ＣＶ法对其性质进行了研究，ＰＤＭｅＡｎ的结构与聚苯胺和聚２，５－二甲氧基苯胺的结构类似，是由其单元通过氮原子（Ｎ）在对位上键合而成，本征态的ＰＤＭｅＡｎ能溶于多种有机溶剂，如ＣＨ２Ｃｌ２、ＣＨＣｌ３、ＤＭＳＯ、ＤＭＦ等。

Poly(2,5-dimethylaniline)(PDMeAn) powder has been synthesized by chemical method. The electric conductivity of polymer was measured by the method of four standard probes.The polymer was characterized by FTIR,UV-Vis spectroscopy and cyclic voltammetry.The structure of PDMeAn is close to that of polyaniline and poly(2,5-dimethoxyaniline),with monomer units linked through the nitrogen atom at para positions.Intrinsic PDMeAn can be dissolved in a variety of organic solvents(DMF,DMSO,CHCl3,CH2Cl2,etc.).It exhibits excellent environmental stability and electrochemical activity.
