摘要:
A fluid filtration material made of a porous substrate, e,g. a membrane or a fabric that is coated with a fluorinated copolymer that contains recurring vinyl alcohol units to impart hydrophilicity. The material is crosslinked with multifunctional epoxides to maintain hydrophilicity on exposure to heat or solvent.
