With the pervasive application of electrical and electronic equipment
the electromagnetic environment around us has become more and more complex
and the demand of electromagnetic shielding materials increases rapidly.Compared with the traditional metal fillers
carbon-based conductive filler has its own unique advantages
such as wide range of sources
light weight and corrosion resistance; so it has a wide application prospect in the field of polymeric electromagnetic shielding materials.In this paper
the structure
property and characteristics of carbon black
graphite
graphene
carbon nanotubes and carbon fibers are introduced. The research progress on carbon-based conductive fillers modified polymeric electromagnetic shielding materials in recent years are summarized from the aspects of filler shape
