摘　　要：以十二烷基萘磺酸(DNSA)为掺杂剂,在醇(或酮)-水介质中采用原位溶液聚合法制备了聚苯胺,以溶液共混法制备了聚苯胺/聚苯乙(PANI/PS)烯复合材料,采用红外光谱、热失重、元素分析和扫描电镜等手段对产物进行了表征.结果表明,掺杂的聚苯胺电导率最高为0.65S/cm,优于常用的十二烷基苯磺酸(DBSA),具有一定的实用价值和理论意义.该复合材料的表面电阻率最低为101Ω/□数量级,并在一定范围内可调,可用于电磁屏蔽,适合于聚合物表面使用.PANI was prepared via in-situ solution polymerization in the solvent system of alcohol（or ketone） water,using DNSA as doping agent.PANI/PS composite were obtained by the solution blend.The products were characterized by TEM,FTIR,elemental analysis and TG.The result show that the maximum conductivity of PANI doped with DNSA was 0.65 S/cm and higher than PANI doped with DBSA.The surface resistivity of composite was adjustable within a certain range and the minimum of it was 101 Ω/□.It can be used for electromagnetic shielding and it is applicable to polymer surface.
