Dielectric Relaxation Spectroscopy of Polyethylene/Lignocellulosic Polymers Blends

摘要

Polymer blends of recycled high density poly(ethylene) (RPE) and wood flour (WF) have been prepared by using 3 types of compatibilizing agents. Dielectric relaxation spectroscopy measurements have been carried out by performing temperature sweeps at constant frequency and frequency sweeps at constant temperature. Incorporation of natural polymers and compatibilizing agent in the polyolefin matrix leads to an increase of conductivity and consequently of the dielectric loss values when comparing with those of matrix.
