Study on comprehensive test of electrostatic properties of graphene coating

Abstract

In this paper, the electrostatic performance of graphene coating samples is comprehensively evaluated and tested, focusing on the resistance (volume resistance and surface resistance) and electrostatic dissipation characteristics of the coating, and the differences of electrostatic performance of coatings with different graphene addition are investigated; The changes of electrostatic properties of graphene coating were studied by simulating vacuum, alternating high and low temperature, UV-vis and other environments. It is found that the content of graphene has a significant effection on the resistance and electrostatic dissipation characteristics of the samples. The higher the content of graphene, the lower the resistance and the shorter the electrostatic decay time; Vacuum, high and low temperature alternating environment have little effection on the electrostatic performance of graphene coating, but UV-Vis radiation has influence on them.
