▎ 摘　　要

NOVELTY - Surface molecularly imprinted polyionic liquid comprises nitrogen-doped graphene-carbon nanotube nitride composite, functional monomer, crosslinking agent and template molecule; prepared by polymerizing under the action of initiator, and removing template molecule. The functional monomer is brominated 1-vinyl-3-ethyl imidazole. The crosslinking agent is ethanediol dimethylacrylate and brominated 1,4-butane-3,3'-bis-1-vinyl imidazole. The template molecule is 4-nonylphenol. USE - Surface molecularly imprinted polyionic liquid used for manufacturing electrochemical sensors for detecting 4-nonylphenol (claimed) and nitrogen-doped graphene/carbon nanotube-molecularly imprinted polymer sensor. ADVANTAGE - The sensor has good adsorption capacity and selectivity, 4-nonylphenol detection range of 0.01-10 mu M and detection limit of 0.005 mu M.
