Polymers are usually electrically insulating materials with a surface electrical resistivity of over 1012 Ωcm. However, in some specific applications, polymers require lower surface resistance, which is achieved by dispersing fine metal powders such as Al, Cu, Ag, etc. or fine carbon particles in the polymer resin. In some cases, carbon fibers or steel fibers have also been used.
Such polymer composites are classified based on the surface or volume electrical resistivity within the range of the final cross-sectional
area of the polymer composition. Polymeric materials are divided into four general categories of insulating materials based on the surface resistance range (surface resistance higher than 1012 Ω sq-1)
Antistatic materials (surface resistance between 109 and 1012 Ω sq-1)
Electrostatic Discharge (ESD) (surface resistance between 106 and 1109 Ω sq-1)
and conductive materials (surface resistance less than 106 Ω sq-1) are divided.
Since an electrically conductive plastic material is formed by diffusing a conductive material into the insulating plastic,
It turns out that if the distribution of the conductive material is inhomogeneous, their electrical conductivity can vary greatly in different regions (Sekhar Rout, 2021).
