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.
Claims14
A method for manufacturing an inverse opal structure membrane filter, the method comprising the steps of:
- charging nanoparticles;
- oppositely charging sacrificial particles;
- mixing a nanoparticle dispersion solution including the nanoparticles and a sacrificial particle dispersion solution including the sacrificial particles to form a mixed solution;
- applying the mixed solution onto a substrate and drying the mixed solution;
- and
- heat-treating the mixed solution to form an inverse opal structure by removing the sacrificial particles,
- wherein the inverse opal structure includes pores that are formed by the removal of the sacrificial particles.
