▎ 摘　　要

NOVELTY - The film has a solid material layer (1) formed with multiple through-holes and manufactured as multiple tree structures. Twenty-five branch holes (3, 4) are fixed with a main hole (2) in parallel, where surface material of the main hole is similar to surface material of each branch hole. Surfaces of the main hole and the branch hole are coated with coating liquid. The main hole and the branch hole are located along thickness direction of the solid material layer. The solid material layer is provided with a filter film that is made of silicon dioxide or graphene. USE - Liquid-liquid separation tree-type nano-cylindrical pore filtration film. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a liquid-liquid separation tree-type nano-cylindrical pore filtration film in partial section. Solid material layer (1) Main hole (2) Branch holes (3, 4)
