摘　　要：结合有机质子酸掺杂,通过化学氧化聚合的方法得到了油溶性的聚苯胺。得到的聚苯胺在Ⅰ类基础油中有良好的溶解分散性能和贮藏稳定性。防锈测试结果表明,油溶性的聚苯胺与合适添加剂复配后,表现出十分优异的防锈性能,与黏度指数改进剂OCP复配(即提高油品体系黏度),能显著提高润滑油的电化学性能;与羊毛脂镁皂复配,在<10%的总加剂量下,盐雾防锈期能达到15天。Oil-soluble polyaniline（PAN）,which is soluble and steady in Group I base oil,was prepared by chemical oxidative polymerization in the presence of organic protonic acid.Combined with suitable lubricant additives,the PAN showed outstanding anti-rust capability in mineral oil.Combined with viscosity index improver（OCP）,the PAN resulted in a visible improvement of the electrochemisty property.When the total content of PAN and lanolis magnesium soap in lubricant was10%（w/w）,the duration in salt frog was up to 15 days in anti-salt spray test（SH/T 0081-91）.
