NOVELTY - Preparing mixed matrix membrane having heat resistance and solvent resistance involves using mixed base film original film and thermally oxidizing and crosslinking, where mixed base film original film is prepared by oxidizing graphene, metal alkoxides, acetic acid, polymers and organic solvents arranged into a film-making solution to obtain film and original matrix of the mixed matrix is synthesized by a non-solvent phase inversion method in situ. USE - Method for preparing mixed matrix membrane having heat resistance and solvent resistance (claimed). ADVANTAGE - The method enables to prepare mixed matrix membrane having heat resistance and solvent resistance which has high permeation separation performance, and has excellent solvent resistance and heat resistance.
