Study on conductive properties of composites based on the in-mold laminating technology

摘要

This paper introduced a new co-extrusion process which could increase layers by lamination-torsion-combination of polymer melt. The in-mold laminating technology was a kind of microlayed co-extrusion technology. The feasibility of the new technology on processing of polymer was validated. Conductive polypropylene filled with carbon black/polypropylene (PPCB/PP) composites was prepared using the novel device, the effects of processing parameters on conductivity of composites were researched. The results showed that the percolation threshold can decrease greatly.
