く、また成型品の表面平滑性及び研摩性において劣る。(Conventional technology) With the development of science and technology and the diversification of needs, the development of high-performance, multifunctional materials is actively being carried out, and even in the plastics industry, various i7F studies are being conducted on the development of conductive polymer materials. For example, polymer materials using carbon particles or fibers or metal powders such as copper, silver, and gold as conductive fillers have been proposed. However, carbon particles, carbon fibers, and metal powders such as copper, silver, and gold all have a color tone unique to the metal, such as black, so there are restrictions on their uses. Moreover, these conductive fillers, except for carbon fibers, do not have reinforcing properties.Although carbon am is a reinforcing conductive filler, it is difficult to arrange the fibers uniformly, and the aspect ratio is low. Because of the irregularities, molding processability is poor, and the surface smoothness and abrasiveness of the molded product are poor.
