摘　　要：采用水相分离法中的单凝聚法制备了以明胶、聚乙烯醇为囊壁材料,润滑油、缓蚀剂、憎水剂等为囊心材料的液体微胶囊,并与镀铜、镀镍液中的金属离子复合电沉积得到含有高耐腐蚀性能的复合镀层。通过比较,含有防锈润滑油微胶囊的复合镀镍层在5%NaCl溶液中出现腐蚀锈点的时间是普通镀镍层的40倍以上;含苯并三氮唑缓蚀剂的微胶囊复合镀铜层耐氨水点滴及硝酸点滴腐蚀时间是普通镀铜层的3倍左右;含憎水剂微胶囊的复合镀铜层在硫酸溶液中的电极电位随时间变化规律和阳极极化曲线表明,其比普通镀铜层具有更好的耐腐蚀性。Microcapsules using Polyvinyl Alcohol （PVA） or inhibitor or hydrophobe as core are prepared by the method sistanee function composite coating by codeposition of these obained. Compared with the rusting time on 5% NaCl soluti glutin as membrane, lubricating oil, of separation in water phase. High benzotriazole corrosion reliquid microcapsules with copper and nickel ions is on, the time of composite nickel coating containing rust preventive oil microcapsules is 40 times that of the nickel coating without mieroeapsule. Compared with the corrosion time on nitric acid and ammonia solution dropping test, the composite copper coating containing benzotriazole inhibitor microcapsules is 3 times that of the copper coating without microcapsule. Anode polarization curve and regularity of electrode potential changing with time on acid copper plating solution are studied and the results show that the composite coating containing hydrophobe microcapsules has higher corrosion-resistance function than copper coating.
