Abstract

1H, 1H, 2H, 2H-perfluorooctyltrichlorosilane (FOTS)-grafted TiO₂/SiC membrane with multiscale super-amphiphobic property was prepared by solvothermal growth followed by dipping treatment. TiO₂ nanocones grown on silicon carbide (SiC) help to ameliorate the surface structure and chemical properties for grafting FOTS. The resulted membrane exhibits super-amphiphobicity with water and oil (n-hexadecane) contact angles of 171.9° and 151.2°, respectively. The static oil adsorption capacity of the membrane is lower than 5%, indicating excellent oil repelling performance. Such an amphiphobic ceramic membrane can be used in long-term oil filtration with comparative low and stable pressure drop (11 kPa) and high rejection rate (98.24%). This work represents a new approach to achieve a super-amphiphobic surface on a solid ceramic membrane, opening a new avenue for the application of oil aerosol removal.
