▎ 摘　　要

NOVELTY - Preparing smart composite hydrogel doped with graphene comprises (i) preparing graphite oxide, (ii) dispersing and stripping the graphite oxide to obtain graphene oxide, and uniformly dispersing the graphene oxide in water to obtain a graphene oxide suspension, (iii) adding ammonium lauryl sulfate and sodium chloride to the graphene oxide suspension for dissolution, further adding octadecyl methacrylate and stirring, and adding N,N-dimethylacrylamide to fully stir the reaction, and (iv) continuously adding initiator potassium persulfate (KPS) and accelerant tetramethylethylenediamine (TEMED), stirring uniformly, adding the solution to a transparent glass test tube, initiating polymerization for 12-18 hours at 50 degrees C to obtain graphene-doped intelligent composite hydrogel PDMA-GOX, where GO is doped with graphene oxide and X is the concentration of GO in the hydrogel. USE - The method is useful for preparing smart composite hydrogel doped with graphene. ADVANTAGE - The method is simple and economical, and has short cycle. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-doped intelligent composite hydrogel PDMA-GOX prepared according to above mentioned method.
