▎ 摘　　要

NOVELTY - The film has an oxide graphene coating layer whose contact angle is maintained on a porous polymer supporter at 20 degrees to 60 degrees. The porous polymer supporter includes UV irradiation, where width of the oxide graphene coating layer is 200-400 nm. USE - Composite film. ADVANTAGE - The fluid path within the oxide graphene coating layer is increased so that gas transmittance at the water transmission degree at the water treatment separation film or the gas separation membrane is remarkably improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a composite film manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a relationship between treatment time and a gas permeation unit. '(Drawing includes non-English language text)'
