Effect of relaxation processes during deformation on electrical resistivity of polyethylene composites filled with carbon black

摘要

This work is dedicated to the study of the influence of the deformation and relaxation processes on electrical resistivity of polyethylene composites filled with carbon black. It was shown that bending deformation of specimens, in particular at elevated temperatures, leaded to the reversible change in electrical resistivity. Obtained results imply relationship between electrical relaxation and mechanical relaxation conditioned by segmental motion of polymers.
