Abstract:The relationship between crystalline structure and positive temperature coefficient (PTC) characteristics was studied in the view of theory and experiment. The effects of the physical properties and processing/post-processing of polymers on the crystalline behavior and PTC characteristics were discussed. The crystallization was a key factor effecting PTC characteristics existing in polymer/carbon black composite.
Keywords:crystalline behavior   PTC characteristics   thermal expansion mechanism   carbon black/polymer composite
