Abstract:

The fabrication methods for conductive polymer/carbon nanotube composites were introduced, including solution blending, melt blending and in situ polymerization. Particular attention was paid on the dispersion of the nanotubes in polymer matrix. Two main electrical properties, conductive percolation and positive temperature coefficient effect were discussed, using polyethylene and epoxy resin based composites as modal systems. The problems existing in processing and the related mechanism were pointed. The development trend of conductive polymer/carbon nanotube composites forecasted.
