▎ 摘　　要

NOVELTY - A surface molecular imprinted polymer ionic liquid is obtained by polymerizing reduced graphene oxide, functional monomer, crosslinking agent and template molecule in the presence of initiator and removing template molecule to obtain a composite material. The functional monomer is 1-vinyl-3-ethyl-imidazolium hexafluorophosphate. The crosslinking agent is ethylene glycol dimethacrylate and 1,4-butane-3,3'-bis-1-vinylimidazolium hexafluorophosphate. The template molecule is bisphenol A. USE - Surface molecular imprinted polymer ionic liquid is used for electrochemical sensor for detecting bisphenol A (all claimed). ADVANTAGE - The surface molecular imprinted polymer ionic liquid has excellent adsorption capacity. The bisphenol A detection range is 0.01-50.0 mu M and detection limit is 0.005 mu M. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of surface molecular imprinted polymer ionic liquid.
