▎ 摘　　要

NOVELTY - Method of printing graphene oxide (GO) on substrate involves producing graphene oxide ink by mixing GO particles with solvent, and printing ink on substrate by expelling droplets of GO ink on substrate. USE - Method of printing graphene oxide on substrate used as medium for filtering water. Can also be used to remove organic contaminants such as endocrine disrupting compounds, pharmaceuticals, personal care products, and salts in water. ADVANTAGE - The substrates printed with GO is economical, and has improved hydrophilicity, high water flux, and enhances separation performance of Go membranes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide membrane.
