▎ 摘　　要

NOVELTY - A graphene oxide antifouling layer based polymer film potential type anti-biofouling sensor comprises conventional disk electrode, polymer sensitive film and graphene oxide layer, where one end of the conventional disk electrode is sequentially adhered to the polymer sensitive film and the graphene oxide layer. USE - Graphene oxide antifouling layer based polymer film potential type anti-biofouling sensor for use in fouling organisms in environmental water body as lake water, river water or sea water. ADVANTAGE - The graphene oxide antifouling layer based polymer film potential type anti-biofouling sensor has improved polymer sensitive film hydrophilic, and can be prepared in simple manner.
