▎ 摘　　要

NOVELTY - Conductive leather or conductive fiber comprises (A) a first layer comprising single-walled carbon nanotubes, graphene nanoparticles and single nanoparticles of silica in such a manner that from 40-60 parts mass single nanoparticles of silica having a size of 5 nm or less as measured by a transmission electron microscope and 60-40 parts mass single nanoparticles of tin oxide having a size of 2 nm or less as measured by a transmission electron microscope are contained with respect to a total of 100 parts mass single nanoparticles of silica and the single nanoparticles of tin oxide, and (B) a second layer comprising a water repellent agent and a conductive material. USE - The conductive leather or conductive fiber is used for touch panel. ADVANTAGE - The conductive leather or conductive fiber imparts electrical conductivity without changing the texture of the base material, while having excellent friction resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing conductive leather or conductive fibers involving (a) using single-walled carbon nanotubes, graphene nanoparticles, silica single nanoparticles, tin oxide single nanoparticles, and water on the surface of leather or fiber for a total of 100 parts mass single nanoparticles of silica and single nanoparticles of tin oxide and measuring single nanoparticles of silica of 5 nm or less with a transmission electron microscope, measuring 40-60 parts mass single nanoparticles of tin oxide of 2 nm or less with a transmission electron microscope and applying a dispersion liquid for forming a first layer comprising 60-40 parts mass to a surface or immersing the surface to form the first layer and (b) applying a second layer forming aqueous solution containing a water repellent, a conductive material, and water to the surface or immersing the surface to form the second layer.
