Abstract: PANI-PVA electric conductive coatings doped with HC1，DBSA and NH2SO3H were prepared，and effect of PANI to PVA mass ratio，acid and oxidant(APS) content，reaction time and drying temperature on the conductivity of coating films were investigated. The conductivity of PANI-PVA coating film was the highest when the mass fraction of PVA was 40% and the film drying temperature was 80℃. The conductivity of HCl-PANI-PVA was 15.0 S/cm when HCl content was 0.5mol/L，reaction time was 6h and APS/An molar ratio was 1.0；The conductivity of DBSA-PANI-PVA was 7.1 S/cm when DBSA content was 1.0 mol/L，reaction time was 8h and APS/An molar ratio was 2.0；The conductivity of NH2SO3H-PANI-PVA was 2.0 S/cm when NH2SO3H content was 1.0 mol/L，reaction time was 6 h and APS/An molar ratio was 2.0. The conductivity of HCl-PANI-PVA was the highest among the three acid doped PANI-PVA electric conductive coatings.

摘要： 采用聚乙烯醇为基质材料，以盐酸、十二烷基苯磺酸、氨基磺酸水溶液掺杂，制备了聚苯胺-聚乙烯醇（PANI-PVA）复合导电涂料。研究了PANI与PVA质量比、酸用量、氧化剂用量、反应时间以及膜干燥温度等因素对涂料膜电导率的影响。结果表明：当PVA质量分数为40%、成膜干燥温度为80 ℃时，PANI-PVA涂料膜的电导率最大。而且当cHCl=0.5 mol/L、反应时间为6 h、过硫酸铵与苯胺摩尔比为1.0时，所得HCl-PANI-PVA膜的电导率达最大，为15.0 S/cm；当cDBSA=1.0 mol/L、反应时间为8 h、过硫酸铵与苯胺摩尔比为2.0时，所得DBSA-PANI-PVA膜的电导率达最大，为7.1 S/cm；当cNH2SO3H=1.0 mol/L、反应时间为6 h、过硫酸铵与苯胺摩尔比为2.0时，所得NH2SO3H-PANI-PVA膜的电导率达最大，为2.0 S/cm。在这几种酸掺杂的PANI-PVA复合导电涂料中，HCl-PANI-PVA膜的电导率最大。
