Effect of electrothermopolarization on relaxation times of nanocomposites based on PP and PE


The effect of electrothermopolarization on the surface density of electret charges and the relaxation time of the charge from the reciprocal temperature for a number of nanocomposites based on PP and PE are studied. It is shown that the addition of a nanofiller (1% MnO2, 0.5% MnO2, 7% ZrO2, 2% TiO2, 1% PbCrO4) leads to an increase in the values of the electret potential difference of nanocomposites, and then decreases. This character of the dependence is explained by a change in the physical structure of the boundary layer of the polymer matrix and a change in the interphase interaction on the strength of the polarization field. The dependence of the charge relaxation time on the reciprocal temperature for all samples has approximately the same slope.

Keywords: nanocomposite, polyethylene, polypropylene, relaxation, electrothermopolarization.
