文摘
- •
PVDF/SiO2 nano-composite membranes were prepared by phase inversion.
- •
PVDF nano-fibres were electro-spun on the nano-composite membrane to form a dual layer membrane.
- •
The dual layer membrane showed increased LEPw and contact angle.
- •
The double layer membrane presented high tendencies to prevent pore wetting.
- •
The DCMD flux was greater than the VMD flux for desalination using the dual layer membrane.
