▎ 摘　　要

NOVELTY - Preparing photo-thermal interface evaporation material comprises (1) uniformly mixing the polymer substrate, aqueous template and photothermal functional filler to obtain a multiphase system, and periodically compressing and releasing the multiphase system to form a composite material with a co-continuous microstructure, (2) loading the modified nanomaterial on the surface of the composite material with a co-continuous microstructure, and (3) immersing the composite material loaded with the modified nanomaterial in water to remove the aqueous template to obtain photothermal interface evaporation material. USE - The method is useful for preparing photo-thermal interface evaporation material, which is useful in seawater desalination or sea surface imitation land planting (claimed). Can also be used for solar interface evaporation field for producing fresh water used in life of organisms on earth. ADVANTAGE - The method: has simple molding process, low material and production cost; can realize the large-scale, continuous and green preparation of the self-floating polymer-based photothermal interface evaporation material and can realize large-scale popularization and application; and has broad market prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a photothermal interface evaporation material.
