Problems solved by technology

[0010] These proposals describe the flexible application of nanofibers. However, although the former has a description of carrying a functional agent in the gap between single fibers, it is an aggregate of ultra-short fibers because it is an alloy fiber. , there are problems in getting sufficient practical
In addition, in the latter case, although nanofibers are used, in the proposed structure, the characteristics of the gap between single fibers are not fully utilized, and the practical durability such as washing durability as a fabric electrode is poor.

Embodiment 1

[0095] Using 100T-136F polyester nanofiber blended yarn to weave circular fabric with double rib weave, the polyester nanofiber blended yarn will use polyethylene terephthalate as island component Alkaline hot water soluble polyester made of a copolymer of terephthalic acid and isophthalic acid-5-sodium sulfonate as the acid component of the ester 75T-112F as the sea component (the sea-island ratio is 30%:70%, The number of islands is 127 islands / F) and nanofibers are blended with 22T-24F high-shrinkage yarns. Next, the fabric was immersed in a 3% by mass sodium hydroxide aqueous solution (75° C., bath ratio: 1:30) to remove easily soluble components to obtain a knitted fabric using mixed yarns of nanofibers and high-shrinkage yarns. By a known gravure coating method, 1.0 wt% of conductive polymer dispersed in a mixed solvent of water and ethanol (44 wt% of water, 50 wt% of ethanol) was coated on the knitted fabric as the obtained fiber structure. Dispersion of PEDOT / PSS and ...

Embodiment 2

[0097] Change the high-shrinkage yarn from 22T-24F to 33T-6F, and use 110T-118F polyester fiber blended with nanofibers and 75T-112F (sea-island ratio: 30%:70%, and the number of islands is 127 islands / F). Except for the ester nanofiber mixed yarn, the same treatment as in Example 1 was performed to manufacture an electrode. Table 1 and Table 2 show the properties of the materials used and the electrodes obtained.

Embodiment 3

[0099] Except for changing the fabric structure from the knitted fabric to the plain weave fabric, the same treatment as in Example 1 was performed to manufacture an electrode. Table 1 and Table 2 show the properties of the materials used and the electrodes obtained.

Abstract

Provided are an electrode member and a device capable of maintaining high electrical conductivity even after repeated washing, and of also being applied as an electrode for an organism. This electrode member is characterized by being a fiber structure configured from a textile or the like including an electroconductive polymer, wherein an electroconductive polymer such as a polythiophene-based electroconductive polymer is supported on the surfaces of single fibers and / or in spaces between single fibers constituting a multifilament used in the fiber structure.

Description

technical field [0001] The present invention relates to an electrode element formed of a fibrous structure and a conductive polymer, and a device using the electrode element. In detail, the present invention relates to a textile electrode element capable of maintaining high conductivity after repeated washing and also applicable to an organism electrode. Background technique [0002] Conventionally, materials made of highly conductive metals have generally been used for electrode elements in view of their required characteristics. With the diversification of applications, various characteristics are required for the shape of the electrode. Among them, in order to make a flexible structure that follows and adapts to various complex shapes, the form of vapor-depositing a thin metal layer on the film, and the metal A flexible electrode base material is known in which an electrode is formed to follow the shape of the base material on which the electrode is placed or pasted by i...
