Abstract: A thin film may include a high toughness and a high air permeability, e.g., when applied to skin, and may be used as a functional member or an electronic functional member. The thin film may include fibers, which may be formed into a net shape constituting a fibrous net, and a coating film, which may be formed on the surfaces of the fibers and in gaps between the fibers. The fibers may be formed by an electrospinning method. The fibers may be formed by using any of a polyurethane, a polyvinyl alcohol (PVA) derivative, and a polyvinylidene fluoride (PVDF) as a material. The coating film may be formed by using polydimethylsiloxane (PDMS) as a material. A conductive film, which may be formed on a part of all of the coating film, may also be provided.

Abstract: [Problem] Provided is an electronic functional member of superior wear resistance. [Solution] The present invention comprises a fiber network constituted by a water-soluble resin and a poorly water-soluble resin, and an electroconductive member formed on the fiber network. The water-soluble resin and poorly water-soluble resin are, for example, polyvinyl alcohol derivatives. In accordance with an embodiment of the electronic functional member according to the present invention, the fiber network is formed by layering a first fiber network constituted by fibers containing a water-soluble first resin and a second fiber network constituted by fibers containing a poorly water-soluble second resin. Alternatively, the fiber network may be constituted by fibers containing the water-soluble first resin and fibers containing the poorly water-soluble second resin. Alternatively, the fiber network may be constituted by fibers containing the water-soluble first resin and the poorly water-soluble second resin.
