NOVELTY - Preparing confinement structure composite material comprises forming nanoporous material layer of a first material and a second material filled in the nanopore, where the difference between the water contact angles of the first material and the second material is greater than 90°, so that the nanopores form a hydrophilic or hydrophobic confinement space. USE - The method is useful for preparing confinement structure composite material. ADVANTAGE - The method is simple, the limitation to the material type is small, the universality is high, which provides a novel idea and way for the preparation of confinement structure composite materials, and has important research and application value.
