NOVELTY - Preparing a hybrid membrane involves adding the high molecular polymer into the solvent under the high temperature stirring condition is configured to disperse uniform, in the presence of oxidant the material with high thermal conductivity and high photo-thermal conversion capability is combined forming a composite material with two properties, the composite material prepared is added into the solution configured, stirring at high speed to make the composite material disperse uniformly in the solution, the solution is ultrasonically transferred to the mould , drying to form film obtaining a hybrid film with strong photo-thermal conversion ability. USE - Method for preparation of hybrid membrane used for solar sea water desalination (claimed). ADVANTAGE - The method provides a hybrid membrane with strong photo-thermal conversion ability, high light absorbing ability, good photo- thermal conversion efficiency and evaporation efficiency, high cycle stability, and salt corrosion resistance and produced with low energy consumption, simple raw material, low cost and easy operation.
