Thin film

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.
