Abstract:
1. A process for producing a nanostructure composite-covered structure including: a step (I-1) in which a solid substrate (X), which is a substrate selected from the group consisting of glass substrates, metal substrates, metal oxide substrates, glass substrates having an etched surface, resin substrates, resin substrates having a surface treated by plasma, resin subtrates having a surface treated by ozone, and resin substrates having a surface treated by sulfuric acid, and resin substrates having a surface treated by alkali, is immersed into a solution containing a polymer (A) having a polyethyleneimine skeleton (a), the solid substrate (X) is taken out of the solution, and a polymer layer is formed on the surface of the solid substrate (X); and a step (I-2) in which the solid substrate (X) having the polymer layer obtained in the step (I-1) is contacted with a source solution (B′) of metal oxide to deposit metal oxide (B) in the polymer layer on the surface of the solid substrate (X) and to form on the solid substrate a nanostructure composite (Y) containing the polymer (A) and the metal oxide (B), wherein the nanostructure composite (Y) is an aggregate containing a composite nano-fiber (y wherein the composite nano-fiber (y wherein the composite nano-film (y
