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.
Claims20
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 each independently comprise a cross-linkable moiety;
- and
- wherein the copolymer is poly((allyl methacrylate)-random-(sulfobetaine methacrylate)), poly((allyl methacrylate)-random-(2-methacryloyloxyethyl phosphorylcholine)), or combinations thereof.
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 each independently comprise a cross-linkable moiety;
- and
- wherein the copolymer is poly((allyl methacrylate)-random-(sulfobetaine methacrylate)), the zwitterionic repeat units constitute 25-75% by weight of the copolymer, and the copolymer has a molecular weight of about 20,000 to about 100,000 Dalton.
