Abstract
Provided are a method of manufacturing an electrically conductive member having excellent properties and such electrically conductive member. A method of manufacturing an electrically conductive member having an electrically conductive film on a surface of a substrate, comprising the steps of: (i) forming a layer containing a colloid on a porous surface of a substrate having at least the porous surface by applying a colloidal solution and (ii) forming an electrically conductive layer by drying the layer containing the colloid.
Claims8
A method of manufacturing an electrically conductive member having an electrically conductive film on a porous substrate, comprising the steps of:
- (i) applying a colloidal solution of a liquid medium and a colloid, said colloid having a core of a metal colloidal particle and a shell of an organic substance to the substrate, wherein a portion of the metal colloid particles move into pores of the substrate and the liquid medium penetrates into the substrate;
- and (ii) drying the colloidal solution on the substrate with hot air or infrared radiation to remove the liquid medium and the organic substance, wherein the portion of the metal colloidal particles in the pores of the substrate in step (i) anchors the metal colloidal particles on the substrate in step (ii).
An electrically conductive member having an electrically conductive film on a porous surface of a substrate, the electrically conductive film being a dried film of a wet applied film containing colloidal particles, wherein the electrically conductive member has portions in contact with an organic semiconductor and wherein a portion of the colloidal particles are present in the pores of the substrate and anchor the colloidal particles forming the film to the surface of the substrate.
