▎ 摘　　要

NOVELTY - A graphene-supported aminotriazole complex having a chlorobenzaldehyde reactive group is obtained by chemically loading oxygen-containing functional active sites to chlorobenzaldehyde-(5-p-methylphenyl-1-amino-(1,3,4-triazolyl)-2-mercapto)-acetylhydrazone and forming complex on graphene molecular layer. USE - Graphene-supported aminotriazole complex is used as corrosion inhibitor for carbon steel and steel product in alkaline concrete environment or alkaline condition (all claimed). ADVANTAGE - The graphene-supported aminotriazole complex with high yield and efficiency is prepared. The carbon steel and steel product formed using the graphene-supported aminotriazole complex has excellent corrosion protection with respect to seawater or sodium chloride medium, with little dosage of graphene-supported aminotriazole complex. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage of graphene-supported aminotriazole complex having chlorobenzaldehyde reactive group as corrosion inhibitor to protect from seawater corrosive medium in alkaline concrete environment or alkaline condition.
