▎ 摘　　要

NOVELTY - Preparing a graphene polymer hydrophilic pretreatment material involves suspending functional monomer 4-amino-3-mercapto-5-mercapto-1,2,4-triazole (AHMT) and the modified chitosan graphene material (GO/CS) in a solvent and oscillating at room temperature for 10-70 hours. The obtained material was centrifuged for 5 minutes, and rinsed with 5% hydrochloric acid, and the washed material is vacuum dried to obtain the graphene polymer hydrophilic pretreatment material. USE - Method for preparing graphene polymer hydrophilic pretreatment material used in analytical detection, drug delivery, and bioimaging. ADVANTAGE - The method enables to prepare graphene polymer hydrophilic pretreatment material, which has a unique triazole ring structure, and has good hydrophilicity.
