▎ 摘　　要

NOVELTY - A graphene nanocomposite with dual intelligent responsiveness is a polygraphene oxide material, and is obtained by polymerizing 1-vinyl-3-ethylimidazolium bromide and N-isopropylacrylamide monomer in presence of azobisisobutyronitrile thermal initiator and methanol as reflux solvent, and then non-covalent modifying pi -bonds between graphene and ionic liquid. USE - Graphene nanocomposite is used in dual-intelligent responsiveness application (claimed) e.g. biosensor, electronic device and separation and purification applications. ADVANTAGE - The graphene nanocomposite has improved dispersibility, excellent temperature sensitivity and intelligent response. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene nanocomposite.
