▎ 摘　　要

NOVELTY - Magnetic graphene oxide/carboxymethyl chitosan compound corrosion inhibitor comprises magnetic graphene oxide and carboxymethyl chitosan at mass ratio of 1-10:40-100. The magnetic graphene oxide is graphene loaded magnetic nanoparticles. USE - Method for preparing magnetic graphene oxide/carboxymethyl chitosan composite corrosion inhibitor used for inhibiting corrosion of steel surface. ADVANTAGE - The magnetic graphene oxide/carboxymethyl chitosan composite corrosion inhibitor greatly improves the corrosion inhibition effect of the corrosion inhibitor by using the interaction force between the magnetic graphene oxide and carboxymethyl chitosan, and effectively reduces the dosage of the corrosion inhibitor which is better for isolating neutral corrosion medium and inhibiting corrosion of steel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparing magnetic graphene oxide/carboxymethyl chitosan compound corrosion inhibitor
