Abstract
The present invention relates to a structural object coated with a superhydrophobic nanostructure composite, the structural object being obtained by densely coating a surface of a solid substrate having a desired shape with a nanostructure obtained by combining a polymer having a polyethyleneimine skeleton with silica on the nanometer order, and bonding a hydrophobic group to the surface of the nanostructure, and a process for producing the structural object. The present invention also relates to a structural object coated with a superhydrophobic nanostructure composite, the structural object being obtained by removing the polymer having the polyethyleneimine skeleton from the nanostructure and bonding a hydrophobic group to the surface of the residual nanostructure containing silica as a main constituent component, and a process for producing the structural object. Furthermore, the present invention provides a method of using the structural object as a container for transferring an aqueous solution.
