Temperature Resistivity

Temperature-resistivity behaviors of carbon black/polyamide 6/high-density polyethylene conductive polymer composites containing electrospun polyamide 6 fibrous network were studied systematically. The positive temperature coefficient intensity of the conductive polymer composites increased firstly and then reduced gradually with increasing heating rate, showing a heating rate-dependent positive temperature coefficient intensity. The fascinating phenomenon was ascribed to the microstructure change of conductive network induced by the volume expansion and the thermal residual stress generated in the composites. During the heating-cooling runs at different top testing temperature of 140, 150 and 180℃, the room-temperature resistivity of sample was observed to be 30, 2.3 and 1.6 orders of magnitude higher than the initial value after one heating-cooling run, respectively. The thermal treatment time above the melting temperature of high-density polyethylene and the viscosity variation of the conductive polymer composites were responsible for the increased resistivity. This study provides a guideline for fabricating conductive polymer composites with tuning positive temperature coefficient property.

Carbon Nanotube Composites

Carbon nanotube (CNT) has been widely used as a kind of conductive inorganic filler in composites due to its excellent mechanical properties, thermal properties and electrical properties. Unfortunately, a deal of CNT is needed because it tends to agglomerate in matrix polymers. And therefore the researchers need to explore appropriate methods to decrease the usage of CNT for its high price. This paper summaries the recent development progress in carbon nanotube filled conductive polymer composites, in aspects of the approaches how to reduce the usage of CNT and application of biodegradable CNT-polymer composites. In addition, the future developing research direction in conductive polymer composites filled with carbon nanotube was indicated.

Conductive Polymer Composites

The electric properties of conductive high density polyethylene (HDPE) composites filled with carbon black were characterized by using frequency spectrum technique. The results show that with increasing carbon black content, the composites exhibit capacitive and inductive features, respectively. On the basis of the observed experimental phenomena, an equivalent inductance - capacitance - resistance (LCR) parallel serial circuit model is proposed
