Abstract
A membrane including a polysulfone/polyethylene terephthalate (PSf/PET) support and an active layer on an outer surface of the PSf/PET support. The active layer comprises reacted units of a diacyl chloride compound, a tetra-amine compound, and a nanocomposite including graphitic carbon nitride and polypyrrole. The membrane of the present disclosure is self-cleaning following exposure to radiation and finds application in water decontamination and de-salination.
Claims18
A porous water decontamination membrane, comprising:
- a polysulfone/polyethylene terephthalate (PSf/PET) support;
