Abstract
The present application relates to a method for manufacturing an inverse opal structure membrane filter, the method comprising the steps of: preparing a mixed solution by mixing a nanoparticle dispersion solution and a sacrificial particle dispersion solution; applying the mixed solution onto a substrate to dry it; and heat-treating the mixed solution, wherein the surface of the sacrificial particles is modified by positive charges or negative charges.
