Abstract: Films of conductive polymer were fabricated based-on styrene-butadiene-styrene triblock copolymer（SBS） and multi-walled carbon nanotubes（MWNTs） regarded as the conductive fillers.The fabrication process,including the selection of solvents,temperature and deposition process,and its effect to shape the surface of the film have been explored.The electrical percolation effect of MWNTs/SBS composite was observed by measuring I-V curves with different relative concentration of MWNTs,and the percolation threshold was obtained between 6~9wt%.Finally the thermal resistivity of the composite was also tested primarily,and it shows strong time-hysteresis.
