摘　　要：分别以双十八烷基二甲基氯化铵和双十二烷基二甲基氯化铵为软模板,采用化学氧化法制备聚苯胺干凝胶。通过傅里叶变换红外光谱(FT-IR)、扫描电镜(SEM)等对聚苯胺干凝胶进行结构表征;将制备的聚苯胺干凝胶应用于水性防腐涂料中,考察其对水性涂料防腐性能的影响。结果表明,制得的聚苯胺水性防腐涂料具有较好的耐水、耐酸、耐碱、耐中性盐雾性。Polyaniline dry gels were prepared by chemical oxidation reaction by using dioctadecyl dimethyl ammonium chloride and didodecyl dimethyl ammonium chloride as soft templates,respectively.The structure of polyaniline dry gels was characterized by Fourier transform infrared(FT-IR)spectroscopy,scanning electron microscopy(SEM).The prepared polyaniline dry gels were applied to waterborne anticorrosive coatings to investigate the effect on the corrosion resistance.The results showed that polyaniline waterborne anticorrosive coatings prepared by the two dry gels had good acid,alkali and salt resistance.
