▎ 摘　　要

NOVELTY - Membrane comprises patterned binder and graphene oxide film, where the membrane optionally comprises filter paper supporting the graphene oxide film. USE - The membrane is used in device for separating solute from solution (claimed) and/or purifying water, and in purification and filtration applications. ADVANTAGE - The membrane has high water permeation rate and enhanced salt rejection, while enhancing the flow of water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) (1) a method for preparing the membrane; and (2) (2) a method for separating solute from solution.
