Preparation of Waterborne Graphite Conductive Coating and Study of Its Electromagnetic Shielding Performance

Abstract:

A waterborne coating of waterborne acrylic resin based material was developed with different sizes of hybrid homemade graphite as conductive filler. Effects on its electrical conductivity and electromagnetic shielding performance were further analyzed and tested, such as conductive filler, coupling agent and iodine addition. The results showed that coating volume resistivity was about 0.05Ω·cm according to the optimal proportion, and attenuation of electromagnetic wave could reach more than 30dB within the frequency range of 1 MHz~1.5 GHz.
