NOVELTY - A polysulfone/thiol-modified mixed matrix film comprises a polysulfone base film, a thiol-based modified graphene oxide/carbon nanotube composite material, which is dispersed in a polysulfone base film. USE - Polysulfone/thiol-modified mixed matrix film. ADVANTAGE - The matrix film is more hydrophilic after being modified by sulfhydryl groups and more hydrophilic in many polar solvents, has better dispersibility, which is dispersed using a variety of solvents that the preparation process is easy to disperse to obtain a uniform mixed matrix film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a polysulfone/thiol-modified mixed matrix, which involves mixing the thiol-based modified graphene oxide/carbon nanotube composite material and the polysulfone solution, subjecting the mixture to fractional ultrasonic dispersion and forming into a film to obtain a polysulfone/thiol-modified mixed matrix film.
