Hydrophobic filter material
Web17 mei 2024 · A hydrophobic surface is one which is water-repellent, with a low surface energy which is resistant to wetting. In order to classify as hydrophobic a material must have a moisture contact angle of a water droplet exceeding 90 degrees. Should this angle exceed 150 degrees then the material is instead classed as superhydrophobic. Web20 feb. 2024 · A superhydrophobic filter material was fabricated via sol-gel method.
