Designs of Zwitterionic Interfaces and Membranes
journal contribution
posted on 2018-07-13, 00:00 authored by Antoine Venault, Yung ChangZwitterionic materials are the latest
generation of materials for
nonfouling interfaces and membranes. They outperform poly(ethylene
glycol) derivatives because they form tighter bonds with water molecules
and can trap more water molecules. This feature article summarizes
our laboratory’s fundamental developments related to the functionalization
of interfaces and membranes using zwitterionic materials. Our molecular
designs of zwitterionic polymers and copolymers, sulfobetaine-based,
carboxybetaine-based, or phosphobetaine-based, are first reviewed.
Then, the strategies used to functionalize surfaces/membranes by coating,
grafting onto, grafting from, or in situ modification are examined
and discussed, and the third part of this article shifts the focus
to key applications of zwitterionic materials. Finally, some potential
future directions for molecular designs, functionalization processes,
and applications are presented.
