Abstract
Disclosed are copolymers, comprising a plurality of zwitterionic repeat units, and a plurality of hydrophobic repeat units, wherein the hydrophobic repeat units each independently comprises a cross-linkable moiety; the cross-linked copolymer network, comprising such copolymer; as well as thin film composite membrane comprising such cross-linked copolymer network.
Claims23
A cross-linked copolymer network derived from a copolymer, comprising a plurality of zwitterionic repeat units, and a plurality of hydrophobic repeat units;
- wherein at least some of the hydrophobic repeat units are cross-linkable repeat units, each independently comprising a cross-linkable moiety selected from an allyl, a vinyl, a vinyl ether, or a vinyl ester;
- and
- wherein the cross-linked copolymer network comprises a plurality of crosslinks derived from reaction of a first cross-linkable moiety with a second cross-linkable moiety.
