Electret State in Composite Polymer Materials Based on Low Density Polyethylene and Polypropylene

Abstract:

The electret state stability in composite polymer materials based on polypropylene and polyethylene with various dispersed inclusions was investigated. It is shown that the surface potential relaxation time of a polymer increases significantly when hydrophilic inclusions are added into its composition. It is assumed that the surface potential relaxation in the initial films occurs due to the volume conductivity which is catalyzed by water molecules within the polymer volume. Introduction of hydrophilic inclusions decreases the volume conductivity of the films as a results of which the stability of their electret state increases.
