Abstract
A method for making an aerogel film includes the steps of performing a gelation reaction of a metal alkoxide on a substrate to prepare a substrate with a wet-gel film, and converting the wet-gel film into an aerogel film by a supercritical or sub-critical drying process of the substrate with the wet-gel film, wherein the degree of gelation of the wet-gel film is controlled to be a predetermined value at the start of the supercritical or sub-critical drying process. Aerogel films having uniform qualities are produced by the supercritical or sub-critical drying process in one lot.
