Abstract: PURPOSE:To perform doping within a short time and obtain a light-weight electroconductive material which can be molded into any desired shape, by molding a melt of a mixture of polypyrroline and a dopant. CONSTITUTION:An electroconductive material is obtained by molding a melt of a mixture of polypyrroline and a dopant. Any dopant that does not cause polypyrroline to decompose can be used, and ones which are liquid at 300 deg.C or below, for example, sulfur trioxide, iodine, bromine trifluoride, arsenic triiodide, and antimony trichloride can be mentioned. The mixing ratio of the polypyrroline to the dopant may be such that the dopant is present in an amount sufficient to melt the polypyrroline and can be readily determined by a preliminary experiment. This melt can be formed into any desired molding by a molding process such as extrusion, pressing, injection, or casting. Said electroconductive material can be used for use in electrodes of primary and secondary cells, or the like, or a variety of electric and electronic components.
