Electrically conductive material and production method therefor, and bioelectrode

Abstract

An electrically conductive material including a base and a conductive polymer applied uniformly to the base's surface and having a reduced resistance value. Specifically, the electrically conductive material includes PEDOT-pTS, serving as a conductive polymer, applied to the base comprised mostly of silk. Also the enclosed provide a method for producing the electrically conductive material, and a bioelectrode including it. The method includes the steps of: (1) applying a p-toluenesulfonate (pTS) solution containing an oxidant component and pTS to a base selected from the group consisting of a silk fiber, a fiber containing sericin or fibroin, and a fiber coated or soaked with sericin or fibroin; and (2) further applying 3,4-ethylenedioxythiophene (EDOT) to the base that already has the oxidant component and pTS applied thereto through the step (1), thereby triggering, at the base, a polymerization reaction to form poly(3,4-ethylene-dioxythiophene)-p-toluenesulfonate (PEDOT-pTS) and applying the formed PEDOT-pTS to the base.
