基于石墨烯的水性导电涂料的制备及其电磁屏蔽性能的研究

Preparation and Electromagnetic Shielding Properties of Graphene Waterborne Conductive Coatings

以丙烯酸树脂乳液为基料,自制石墨烯为导电填料制备了一种水性导电涂料。分析了影响该涂料涂膜导电性及电磁屏蔽性能的因素。按最佳配方制备的导电涂料在0.1~1 000 MHz的频段范围内,对电磁波的衰减在30 dB以上。

The preparation of waterborne electromagnetic shielding （EMS） conductive coatings based on acrylic resin emulsion and self-made graphene was introduced. The influencing factors on the electrical conductivity and electromagnetic shielding properties of the coating film were analyzed. Attenuation of electromagnetic wave by optimal conductive coating formula are above 30 dB at the frequency range 0.1 -- 1 000 MHz .
