Abstract
A method of preparing a hybrid membrane, the method including: evenly mixing a granular material and a dispersant, to yield a dispersion solution; evenly mixing a polymer and an organic solvent, to yield a matrix solution; adding the matrix solution to the dispersion solution to yield a mixed solution; heating the mixed solution to remove the dispersant, to yield a casting solution; and coating the casting solution on a substrate, followed by removal of the organic solvent, to yield a hybrid membrane.
