    • The present invention provides 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. The invention also provides 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.
    • 本发明提供一种导电材料,其包括基体和均匀涂覆在基体表面上并具有降低的电阻值的导电聚合物。 具体而言,导电材料包括用作导电聚合物的PEDOT-pTS,其应用于主要由丝构成的基底。 本发明还提供了用于制造导电材料的方法,以及包括它的生物电极。 该方法包括以下步骤:(1)将含有氧化剂组分和pTS的对甲苯磺酸盐(pTS)溶液施加到选自丝纤维,含丝胶蛋白或丝心蛋白的纤维和纤维包覆的或 用丝胶或丝素蛋白浸泡; (2)通过步骤(1)向已经具有氧化剂组分和pTS的基底进一步施加3,4-亚乙基二氧噻吩(EDOT),由此引发聚合反应以形成聚(3,4-亚乙基二氧噻吩) 4-乙烯 - 二氧噻吩) - 对甲苯磺酸酯(PEDOT-pTS),并将形成的PEDOT-pTS施加到基底上。
