Effect of Coupling Agent Treatment on the Properties of Silicon Carbide Filled LLDPE Composites

Abstract:

Thermally conductive silicon carbide (SiC) filled linear low density polyethylene (LLDPE) plastics were prepared by using powder-mix method. Effects of coupling agent treatment on the thermal conductivity, mechanical properties, morphology and electric properties were also investigated. The results indicate that the coupling agent treatment for SiC particles improves the thermal conductivity of the plastics when using 1 wt.% to 3 wt.% coupling agent. The coupling agent treatment for SiC particles enhances interfacial adhesion between filler and matrix, giving the material higher mechanical properties. The coupling agent treatment for SiC particles also lowers the dielectric constant and dielectric loss of the material, performing better dielectric properties.
