摘　　要：采用了微区交流阻抗技术、扫描电子显微技术与电化学阻抗技术,研究了由聚苯胺/磷酸锌有机-无机复合钝化填料和环氧-聚硅氧烷树脂所制备的自修复涂层的修复和防腐性能。结果表明,环氧-聚硅氧烷清漆涂层具有自修复和优异的耐蚀性能,偶联剂处理的聚苯胺/磷酸锌有机-无机复合钝化填料可显著提升环氧-聚硅氧烷涂层的自修复和耐蚀性能。This paper employs micro-area AC impedance technology, scanning electron microscopy and electro- chemical impedance technology, studies on the repair and anti-corrosion properties of self-healing coating prepared from polyaniline/zinc phosphate organic-inorganic compound passivation packing and epoxy-polysiloxane resin. The results show that the epoxy-polysiloxane varnish coating has self-healing and excellent corrosion resistance. Polyani- line/zinc phosphate organic-inorganic compound passivation packing treated by coupling agent can significantly im- prove the self-healing and corrosion resistance of epoxy-polysiloxane coating.
