CARBON NANOMATERIAL COATED ELECTROMAGNETIC INTERFERENCE SHIELDING COMPOSITES AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A carbon nanomaterial coated electromagnetic interference shielding composites and a preparation method thereof are provided to effectively control the content of the carbon nanomaterial by using a VARTM molder for injecting polymer resin to carbon nanomaterial fiber. CONSTITUTION: A carbon nanomaterial is mixed with methanol(S10). The carbon nanomaterial is coated on the surface of insulation fiber(S20). A VARTM molder injects polymer resin to the carbon nanomaterial coated insulation fiber(S30). The insulation fiber is composed of one among glass fiber, Kevlar fiber and ultrahigh molecular weight polyethylene. The carbon nanomaterial is composed of one among multi-wall carbon nanotube, graphene and exfoliation graphite nanoplate.
