Effects of the preparing process such as coupling treatment, mixed time, radiation dose and annealing on positive temperature coefficient (PTC) properties of HDPE/CB composites were investigated. The results showed that the optimum PTC property could be obtained with 140~160 kGy radiation dose, the uneven dispersion state of CB particle and annealing treatment, PTC intensity was decreased with coupling treatment or the longer mixed time.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=8514856' target='_blank'><b class='type_ico_id'></b></a><a
