摘要/Abstract

摘要： 以盐酸为掺杂剂、过硫酸铵为氧化剂、咪唑类离子液体为稳定剂，采用化学氧化聚合法合成了导电聚苯胺(PANI)颗粒，将其分散到水性环氧树脂(ER)中制成聚苯胺水性环氧防腐涂层，研究了聚苯胺颗粒对涂层防腐性能和机械性能的影响。结果表明，添加聚苯胺显著提高了水性环氧涂层的阻隔性能，信号频率f=0.01 Hz时，PANI/ER涂层的阻抗(|Z|f=0.01Hz)均高于纯ER涂层。添加5.0wt% PANI时ER涂层阻隔性能最好，浸泡0~168 h时|Z|f=0.01Hz稳定在约8.0×108 Ω?cm2，浸泡168 h后|Z|f=0.01Hz=7.5×108 Ω?cm2，远高于ER和其它PANI/ER体系。中性盐雾实验结果表明，聚苯胺赋予了涂层钝化腐蚀的能力，显著提高了涂层的防腐性能，且其添加量越高，防腐性能越好。弯曲和冲击实验结果表明，涂层的机械性能随聚苯胺含量增加先上升后降低，当聚苯胺添加量不超过5.0wt%时，涂层的机械性能优异，附着力和韧性均较好；PANI添加量增至7.0wt%时，ER涂层的脆性明显变大，机械性能下降。聚苯胺在水性环氧体系中的最宜添加量为5.0wt%，此时涂层的机械性能良好，综合防腐性能最优。
