▎ 摘　　要

NOVELTY - Preparing multilayer graphene oxide sheets to protrude an entry of corrosive ions onto a metal surface, comprises: washing and chopping 50-100 g leaf part of Cardiospermum halicacabum; extracting phytocomponents from the chopped leaf part of the Cardiospermum halicacabum using a solvent extraction process; and filtering the phytocomponents which are extracted from the chopped leaf part of the Cardiospermum halicacabum using a Whatman filter paper, synthesizing a multilayer graphene oxide sheet by treating 0.5 g graphene oxide with 10-20 ml phytocomponents obtained from 50-100 g leaf part of Cardiospermum halicacabum, where the phytocomponents modifies a property of the graphene oxide and stacks into the multilayer graphene oxide sheet. USE - The process is useful for preparing multilayer graphene oxide sheets to protrude an entry of corrosive ions onto a metal surface. ADVANTAGE - The process is cost-effective, and time-saving. DESCRIPTION OF DRAWING(S) - The figure shows a flow diagram of preparing a multilayer graphene oxide sheets to protrude an entry of corrosive ions onto a metal surface.
