文摘
A novel polyvinylidene fluoride (PVDF) ultrafiltration membrane with photocatalytic and antibacterial properties was prepared by phase inversion. The in situ formed silver (Ag) nanoparticles were immobilized with titanium dioxide (TiO2) nanoparticles. And the modified PVDF membranes were fabricated by adding Ag–TiO2 into the casting solution. Results showed that the surface contamination of membrane can be degraded effectively by photocatalysis method. Compared with the pristine membrane, the hydrophilicity of modified membrane was improved. Besides, the modified membrane had an excellent antibacterial property. Therefore, the novel Ag–TiO2–PVDF membrane has a very promising application perspective.
