▎ 摘　　要

NOVELTY - Method for manufacturing an inverse opal structure membrane filter involves 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, where the surface of the sacrificial particles is modified by positive charges or negative charges. USE - Method for manufacturing an inverse opal structure membrane filter for use in water purification system (claimed). ADVANTAGE - The inverse opal structure membrane filter has high flow rate and increase the amount of water purification. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a inverse opal structure membrane filter manufactured by the manufacturing method; and a water purification system in which two or more inverse opal structure membrane filters are stacked and disposed.
