▎ 摘  要

NOVELTY - Preparation method of deionized electrode material, involves ultrasonically dispersing graphene oxide nanosheets in an organic solvent, heating while stirring and dripping 3-(methacryloyloxy)propyltrimethoxysilane, immersing into liquid nitrogen to completely freeze and dry, and obtain graphene oxide nano-coil, centrifuging polystyrene emulsion, removing supernatant, drying the precipitate to obtain orderly arranged polystyrene template, soaking in metal salt/methanol solution, drying, soaking in ligand/methanol solution, leaving still to obtain polystyrene/organic framework composite, adding the composite to dimethylformamide, stirring to remove polystyrene and obtain three-dimensional ordered macroporous organic framework material, ultrasonically processing the nano-coil in water containing polydiallyldimethylammonium chloride, filtering, vacuum drying to obtain modified nano-coil, mixing with the framework material in tetrahydrofuran, centrifuging, washing, and heating. USE - Preparation method of deionized electrode material for capacitors. ADVANTAGE - The electrode material has higher specific surface area, good pore structure and mechanical strength, and good electrical conductivity, and has excellent performance as an electrode. DETAILED DESCRIPTION - Preparation method of deionized electrode material, involves ultrasonically dispersing graphene oxide nanosheets in an organic solvent, heating in a water bath, while stirring and dripping 3-(methacryloyloxy)propyltrimethoxysilane, quickly immersing into liquid nitrogen to completely freeze and dry, and obtain graphene oxide nano-coil, centrifuging polystyrene emulsion, removing supernatant to obtain precipitate, drying the precipitate for one night to obtain orderly arranged polystyrene template, soaking in 0.05 mol/L metal salt/methanol solution for 2-4 hours, drying for one night, soaking in 0.08 mol/L ligand/methanol solution, leaving still for 40-48 hours to obtain polystyrene/organic framework composite, adding the composite to dimethylformamide, stirring for 12-18 hours to remove polystyrene and obtain three-dimensional ordered macroporous organic framework material, ultrasonically processing the nano-coil in 50 ml ultrapure water containing 1% polydiallyldimethylammonium chloride for 5 hours, filtering, vacuum drying to obtain modified nano-coil, mixing with the framework material in a mass ratio of 1:5 in tetrahydrofuran at room temperature under argon protection for 5 hours, centrifuging, washing with tetrahydrofuran, and heating under nitrogen protection.
