▎ 摘  要

NOVELTY - Preparing super-hydrophobic low- adhesion material, involves (a) putting the self-supporting substrate in the anhydrous ethanol, ultrasonically processing for 20-40 minutes, then taking out the substrate from the anhydrous ethanol, replacing the new anhydrous ethanol and then placing the substrate in the ultrasonic treatment for 20-40 minutes, repeating the process for 3-5 times; (b) mixing the hydrophobic bonding agent into the organic solvent ultrasonically for 20-40 minutes to obtain the solution A, then uniformly dispersing the micron carbon material and the photo-catalytic nano particles in the solution A to obtain the mixed solution B; (c) putting the clean substrate obtained in the mixed solution B obtained, ultrasonically processing for 30 to 60 minutes, then taking out the substrate from the mixed solution B, vacuum drying to obtain the super-hydrophobic low-adhesion material. USE - Method for preparing super-hydrophobic low- adhesion material used in solar photo-thermal water evaporation, seawater desalination, sewage purification or antibacterial adhesion (claimed). ADVANTAGE - The method for preparing super-hydrophobic low- adhesion material is cost-effective, has photo-thermal photo-catalytic synergistic effect. The super-hydrophobic low- adhesion material has good scalability, stability and preparation convenience. DETAILED DESCRIPTION - Preparing super-hydrophobic low- adhesion material, involves (a) putting the self-supporting substrate in the anhydrous ethanol, ultrasonically processing for 20-40 minutes, then taking out the substrate from the anhydrous ethanol, replacing the new anhydrous ethanol and then placing the substrate in the ultrasonic treatment for 20-40 minutes, repeating the process for 3-5 times, in the process of anhydrous ethanol-ultrasonic-taking-out substrate- replacing waterless ethanol, taking out the substrate after the last ultrasonic wave, placing in the deionized water, then taking out the substrate from the deionized water, replacing the new deionized water and placing the substrate in the ultrasonic treatment, taking out the substrate after the last ultrasonic wave, naturally drying to obtain clean substrate; (b) mixing the hydrophobic bonding agent into the organic solvent ultrasonically for 20-40 minutes to obtain the solution A, then uniformly dispersing the micron carbon material and the photo-catalytic nano particles in the solution A to obtain the mixed solution B; (c) putting the clean substrate obtained in the mixed solution B obtained, ultrasonically processing for 30 to 60 minutes, then taking out the substrate from the mixed solution B, vacuum drying to obtain the super-hydrophobic low-adhesion material. An INDEPENDENT CLAIM is included for a super-hydrophobic low-adhesion material with photo-thermal photo-catalytic synergistic effect, which is prepared by the method.
