ELECTRICAL CONDUCTIVITY OF THE ELECTRODEPOSITED COPPER POWDER FILLED LIGNOCELLULOSIC COMPOSITES

摘要: This article deals with the synthesis and characterization of electroconductive composite materials prepared by compression molding mixtures lignocellulose electrochemically deposited copper powder under different pressures, as well investigation influence particle morphology on conductivity percolation threshold obtained composites. Electrodeposited content varied from 1.9-29.4 vol%. The analysis most significant properties composites its components included impedance spectroscopy (IS) behavior, measurements electrical conductivity, scanning electron microscopy (SEM) structural analysis. It has been shown that (PT) depends both shape type spatial distribution. IS SEM have particles pronounced grain boundaries a bit effect appearance electric conductive pathways thus conductivity. packaging more interparticle contact lead to “movement” PT, which, for <45 μm highest processing pressure 27 MPa, was 7.2% (v/v).
