High- strength composite nanosheet film , transparent superhydrophobic film and its manufacturing method using the same

摘要

PROBLEM TO BE SOLVED: To provide a high-strength composite nanosheet film, a water-superrepellent transparent film using the same, and a method for manufacturing the same.;SOLUTION: The high-strength composite nanosheet film is obtained by conducting a sintering treatment on a two-layer structure comprising an aluminum oxide particulate layer film formed on an Al compound nanosheet produced by a hot-water treatment of a metal Al film formed on a substrate. Alternatively, the high-strength composite nanosheet film is obtained by conducting a sintering treatment on a two-layer structure comprising a new aluminum oxide particulate layer film further formed on an aluminum oxide nanosheet film formed by a heat treatment of an Al compound nanosheet film produced by a hot-water treatment of a metal Al film formed on the substrate. The water-superrepellent transparent film is obtained by using a transparent substrate as the substrate and coating a surface of a nanosheet fine structure located at a surface of the high-strength composite nanosheet film with a low-polarizability silane compound.;COPYRIGHT: (C)2012,JPO&INPIT
