Abstract
In reduced size of electronics devices, it is indispensable to develop electroconductive plastic with light weight. The development of electroconductive plastic which utilized the carbon materials such as CB as electroconductive filler has been carried out. Electroconductivity of polymer sheet filled with nano meter sized carbon fiber (Exfoliated Carbon Fibers: ExCFs) was examined in this study. The sheet which dispersed ExCFs expressed the electroconducting in the addition which is less than the sheet dispersed CB. In addition, the improvement of the electroconductivity was recognized for re-heat treatment of ExCFs with graphitization.
