TL;DR: In this paper, a crosslinked polymeric hydrogel with grafted side chains was used to induce rapid de-swelling by tailoring the polymeric gel architecture at the molecular level.

TL;DR: In this paper, the deswelling response on raising the temperature of this gel above the gel phase transition temperature (TP) takes place within 10 min, whereas a conventionally cross-linked PIPAAm gel of the same dimensions requires 1 month.

TL;DR: Amino semitelechelic poly(N-isopropylacrylamide)s (PIPAAm) with three different molecular weights were synthesized by telomerization of IPAAm monomer with 2-aminoethanethiol as a chain transfer agent as mentioned in this paper.

TL;DR: In this paper, the authors investigated the shrinking kinetics of copolymer gels with the hydrophilic comonomer, acrylamide, and hydrophobic comonomers, butyl methacrylate, and found that the shrinking process is dominated by polymer network diffusion.

TL;DR: Two types of thermo-responsive hydrogels are synthesized to obtain comb-type grafted gels with different lower critical solution temperatures (LCSTs) between graft chains and cross-linked backbone networks and the effect of graft chain hydrophilic/hydrophobic balance as well as its mobility on deswelling kinetics are investigated through the polymer LCST modulation and external temperature changes.
