▎ 摘　　要

NOVELTY - Temperature-sensitive graphene-based electrochemically modified material is ferricyanide/poly-reduced graphene oxide. USE - Temperature-sensitive graphene-based electrochemically modified material for electrochemical sensor (claimed), electrochemical analysis, biosensing, electronic devices, separation and purification. ADVANTAGE - The temperature-sensitive graphene-based electrochemically modified material has good dispersibility, and the graphene is provided with higher reduction state, and imparts two kinds of intelligent responsiveness to temperature sensitivity and ionicity of the material, and the material is applied to the biosensor. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing a temperature-sensitive graphene-based electrochemical modification material, which involves using thermal initiator of azobisisobutyronitrile, dimethylformamide as a reflux solvent, using ionic liquid 1-vinyl-3-butylimidazolium bromide BVImBr and block copolymer PNIPAM to form block copolymer poly(NIPAM-b-BVImBr), using the pi-pi non-covalent modification between graphene and ionic liquid to prepare a polymerization product poly-reduced graphene oxide and synthesizing temperature-sensitive graphene-based electrochemical modification material ferricyanide/poly-reduced graphene oxide by anion exchange reaction; and (2) use of the temperature-sensitive graphene-based electrochemically modified material is claimed for electrochemical sensor.
