In a continuation of previous work conducted at the Centre on coated membranes we have developed a superhydrophobic membrane for application in membrane distillation. The membrane has been created to give a hierarchical structure with multilevel roughness via depositing TiO2Ìýnanoparticles on microporous PVDF. The TiO2 coated membranes were then fluorosilanized by using a low surface energy material.
The anti-fouling performance of virgin and modified membranes were examined in a direct contact membrane distillation (DCMD) process using sodium chloride and humic acid solution as model foulants. Results showed that the modification was mechanically and thermally robust and photoactive. The LEP and water contact angle after the fluorosilanization of TiO2 nanocomposite PVDF membranes.
