The effect of cooling rate after polymer melting on the electrical properties of high-density polyethylene (HDPE)/Ni conductive polymer composites was investigated. Ni particles in HDPE/Ni composites are localized into the amorphous matrix of HDPE. Therefore, conductive paths are formed effectively by increasing HDPE crystallinity. It was found that the resistivity at room temperature of slowly cooled samples is lower than that of quenched samples because the crystallinity of HDPE in slowly cooled samples is higher than that in quenched samples.
