Temperature-responsive shrinking kinetics of poly (N-isopropylacrylamide) copolymer gels with hydrophilic and hydrophobic comonomers
TLDR
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.About:

Rapid Deswelling Response of Poly(N-isopropylacrylamide) Hydrogels by the Formation of Water Release Channels Using Poly(ethylene oxide) Graft Chains
Yuzo Kaneko,Satoki Nakamura,Kiyotaka Sakai,Takao Aoyagi,Akihiko Kikuchi,Yasuhisa Sakurai,Teruo Okano +6 more
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.

Studies on anion exchange membranes having permselectivity for specific anions in electrodialysis — effect of hydrophilicity of anion exchange membranes on permselectivity of anions
TL;DR: Permselectivity of specific anions through the anion exchange membranes is governed mainly by the balance of hydration energy of anions with hydrophilicity of the membranes, partially by hydrated ionic size of the anions, except the membranes having an oppositely charged layer on the membrane surface.

Tunable swelling kinetics in core--shell hydrogel nanoparticles.
TL;DR: The results suggest that the core--shell architecture is a powerful one for the design of colloidal "smart gels" with tunable properties and the formation of a thin, stable skin layer at the particle exterior during the early stages of particle collapse is the rate limiting factor in particle deswelling.

Solution Properties of Poly(N-isopropylacrylamide)
M. Heskins,J. E. Guillet +1 more
TL;DR: In this paper, a lower critical solution temperature of poly(N-isopropyl acrylamide was found to be due to an entropy effect, which was attributed to the formation of nonpolar and intermolecular hydrogen bonds.

Thermally on-off switching polymers for drug permeation and release
TL;DR: In this article, the swelling of crosslinked poly(N,N-alkyl substituted acrylamides) in water was studied in relation to changes in external temperature, and significant swelling changes of the polymer in water in response to temperature can be attributed to the delicate hydrophilic/hydrophobic balance of polymer chain, and was affected by the size, configuration and mobility of the alkyl side chains on the substituted acylamides.
