Resistivity-temperature characteristics of CB/HDPE composites crosslinked by irradiation of electron beam were studied. The results showed that CB/HDPE gel composites, which were generated through extraction by xylene for crosslinked samples, exhibited much higher PTC intensity and distinctive NTC effect during the first heating-cooling cycle. But much better stability of resistivity as well as diminished NTC effect were observed when the composites was exposed to heating-cooling cycles subsequently. The phenomena observed above were related to the structure stability of the gel, suggesting that crosslinking of the polymeric matrix is an effective method to stabilize conductivity and alleviate NTC effect for polymer composites filled with conductive particles.
