NOVELTY - Preparation of metal-organic framework-modified graphene/polymer hybrid proton exchange membrane comprises adding metal organic framework-modified graphene to polymer solution and ultrasonic dispersing to obtain casting solution; carrying out coating deposition, placing in oven at 60-70 degrees C, and heating to 110-150 degrees C; vacuumizing at 12-36 hours; and soaking in hydrogen peroxide solution and acid and activating. USE - Method for preparing metal-organic framework-modified graphene/polymer hybrid proton exchange membrane (claimed). ADVANTAGE - The proton exchange membrane effectively increases proton conductivity, inhibits methanol permeability, avoids formation of multi-layer graphene, increases proton transfer rate, and has selectivity function. The method is simple, has mild condition, and is easy to mass produce.
