Designing Hydrogels by ATRP
Haifeng Gao, Nicky Chan, Jung Kwon Oh and Krzysztof Matyjaszewski
Abstract
This review summarizes the recent progress on the synthesis and
application of covalently crosslinked hydrogels prepared using atom trans-
fer radical polymerization (ATRP) technique. ATRP has been employed as an
effective means to synthesize well-controlled polymeric materials with narrow
molecular weight distributions, compositions, chain-end functionalities, and
macromolecular architectures. These ATRP-processed materials include not only
linear polymer chains but also various branched architectures such as star, gra-
dient, and graft copolymers with a very high grafting density. The techniques
can be successfully used in water under homogeneous or heterogeneous condi-
tions opening new avenues for the preparation of hydrogels and other networks,
including functional materials, responsive, injectable and supersoft elastomers
suitable for multiple bio-related applications.
