摘要: 以DNSA掺杂剂,在醇(或酮)-水介质中采用原位溶液聚合法制备出了聚苯胺,以溶液共混法制备出了聚苯胺/聚苯乙烯复合材料,采用红外光谱、热失重、元素分析、扫描电镜对产物进行了表征。结果显示:掺杂的聚苯胺电导率最高为0.65 S/cm,优于常用的DBSA,具有一定实用价值和理论意义。该复合材料表面电阻率最低为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。

Abstract: 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, elementary analysis and TG. The result showed that the maximum conductivity of PANI doped with DNSA is 0.65 S/cm and higher than PANI doped with DBSA. The surface resistivity of composite is adjustable within a certain range and the minimum of it is 101Ω/□. It can be used for electromagnetic shielding and it is applicable to polymer surface.
