▎ 摘　　要

NOVELTY - Preparing hydrophilic PPy/3DRGO/WSP5 composite material involves dispersing water-soluble cationic quaternization column 5 aromatic hydrocarbon in the graphene oxide aqueous solution. A pyrrole is added to the solution, stirred until mixed uniformly, and hydrothermally reacted at 90 °C for 3h. The mixture is centrifuged and washed to obtain hydrogels after the reaction is over followed by freeze-drying to obtain a hydrophilic PPy/3DRGO/WSP5 aerogel composite material. USE - Method for preparing hydrophilic PPy/3DRGO/WSP5 composite material for use in the electrochemical detection of carbendazim (claimed). ADVANTAGE - The method has excellent dispersibility, conductivity and electrochemical performance, and is easy to form under the condition.
