▎ 摘　　要

NOVELTY - An amino acid-graphene oxide composite corrosion inhibitor comprises amino acid and graphene oxide with mass ratio of (10-1000):1. The amino acid is L-serine. USE - Amino acid-graphene oxide composite corrosion inhibitor used in corrosion inhibition of metal e.g. copper material (all claimed) in acid or seawater conditions. ADVANTAGE - The composite corrosion inhibitor is environmentally-friendly and has low toxicity raw materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) system with corrosion inhibiting property; (2) system configuration method; and (3) usage of amino acid-graphene oxide composite corrosion inhibitor in corrosion inhibition of metal.
