摘　　要：随着电子信息技术的发展,电磁干扰和电磁辐射影响着生产和信息安全以及人们的健康,因此电磁波屏蔽已成为研究的热点。水性导电涂料是一种有效且绿色环保的电磁屏蔽涂料。综述了镍系、铜系、碳系和复合型水性电磁屏蔽涂料的组成、特点、存在的问题及发展状况。镍系水性涂料电磁屏蔽性能和抗氧化性能良好,是当前水性电磁屏蔽涂料的主流;铜系水性涂料导电性好,但抗氧化性差,如何防止铜在水中的氧化是当前铜系水性涂料制备的关键技术问题;碳系水性涂料的耐腐蚀性好,密度小,价格低,但导电性相对较差,电磁屏蔽性能不显著,纳米石墨微片的表面改性处理是增强碳系涂料电磁屏蔽性能的重要手段;复合型导电涂料成本低、电磁屏蔽性能高,是今后水性涂料的主要发展方向。With the rapid development of the electronic industry, electromagnetic interference and electromagnetic radiation are becoming increasing problem that affects people＇s health, the production security and information security. So the electromagnetic interference shielding is increasingly required. Waterborne conductive coatings are electromagnetic shielding ones with the efficient and green environmental protection features. This article gives an overview of the constitution, feature, existent problems and research situation of nickel-base, cuprum-base, carbon-base and composite waterborne electromagnetic shielding coatings. It points out that the nickel-base waterborne coating which has a high property of electromagnetic shielding and anti-oxidation is the main development trend. The cuprum-base waterborne coating has an excellent conductibility, however, anti-oxidation in water for copper is a key technology to preparing the coating. Carbon-base waterborne coating with low density and price can exhibit high anti-corrosion property. Nevertheless, this coating has a deficient conductibility and inapparent electromagnetic shielding property, and surface modification of graphite nano-sheet is an important method to enhance its electromagnetic shielding property. Composite shielding coatings which have a low cost and high electromagnetic shielding properties present the main development tendency of waterborne electromagnetic shielding coatings in the future
