论文摘要
传统涂料由于含有铅或铬酸盐等有毒物质,在制备和应用过程中存在环境污染的危险。因此,开发新型的高耐蚀涂层材料及其绿色制备技术成为金属腐蚀与防护领域所追求的目标之一。聚苯胺(PANI)以其成本低,合成简单,高化学稳定性和环境稳定性,可在绝缘体转变为导体之间转换(通过质子酸掺杂/脱掺杂)等性能,成为近年来国内外学者研究的焦点。研究结果表明,PANI是一种性能优良的防腐材料,其氧化性能够氧化钢铁表面形成钝化层,其中的掺杂剂能够释放出来作为缓蚀剂或形成致密钝化膜的辅助试剂,代替传统涂料中的铅或铬酸盐等有毒物质。PANI独特的纳米形貌的研究和应用也是近几年来的研究热点,其不同形貌的控制制备不仅对控制PANI的性质与应用有重要意义,对控制其他材料的控制制备也有指导作用。利用表面活性剂在不同浓度下形成不同形状的胶束作为模板制备纳米材料是当今材料控制制备领域的研究热点问题。咪唑啉类衍生物是一类阳离子表面活性剂,在酸性条件下也是一种性能优良的缓蚀剂。本文首次研究了咪唑啉类表面活性剂对PANI的纳米形貌的影响,考查了苯胺单体浓度,反应温度,酸度,咪唑啉的临界胶束浓度等一系列因素对PANI纳米结构的影响。成功合成了PANI纳米线,对PANI纳米线的形成机理进行了探讨。按照一定配方制得PANI/环氧树脂涂料。利用开路电位时效法、动电位扫描Tafel极化曲线、交流阻抗等电化学方法,考查了涂料在碳钢表面的防腐性能(3.5%NaCl溶液)。实验结果表明,该涂料具有优异的防腐性能。
