Electrical conduction in carbon loaded polyethylene

摘要

It is well known that the addition of conducting particles such as “carbon black” can substantially increase the electrical conductivity of various insulating materials. 1–3 At relatively high carbon loading the conductivity undergoes large increases, presumably when the random packing of the particles leads to infinite conducting chains.4 This report deals with the conduction properties of 3% carbon loaded polyethylene where the basic insulating characteristics of the host material are unaltered, except that uniformly distributed conducting centers may give rise to slightly higher levels of conduction.
