▎ 摘　　要

NOVELTY - Method for preparing polyacrylamide gel with a controllable pore size, involves mixing graphene oxide, acrylic acid, thionyl chloride, hydroquinone and triethylamine, synthesizing under a protective gas atmosphere to obtain acrylic functionalized graphene, dissolving the acrylic functionalized graphene in dimethylformamide to obtain a dimethylformamide solution of functionalized graphene, and mixing functionalized graphene in dimethylformamide solution, acrylamide, N-isopropylacrylamide aqueous solution, tris(hydroxymethyl)aminomethane (Tris) hydrochloride, sodium dodecyl sulfate (SDS), Triton X-100 (RTM: t-octyl phenoxy polyethoxy ethanol), photosensitive compound MAP-mPyTC, ammonium persulfate (APS) and tetramethylethylenediamine (TEMED) gel under anaerobic conditions. USE - The method is useful for preparing polyacrylamide gel with controllable pore size (claimed). ADVANTAGE - The method provides reversible adjustment of the gel size, and short required change time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for polyacrylamide gel with controllable pore size, which is prepared by the method.
