The present invention discloses a method for forming a low biofouling filtration membrane. First, an ozone treatment is performed to a fluorine-based porous membrane to introduce peroxides on surface. Afterwards, a first grafting polymerization is initiated from the peroxides, and functional monomers are polymerized to introduce halide groups on surface. Finally, a second grafting polymerization is initiated from the halide groups, and macro-monomers are polymerized to introduce zwitterionic group on surface, so as to form the low biofouling filtration membrane. |
