“…23% non-freezing water on chitosan-PEO hydrogel, [61] 24-28% non-freezing water on a chitosan hydrogel, [144] 35% non-freezing water in HEMA hydrogels and as high as 43% non-freezing water in DHPMA hydrogels are observed. [154] The molecules of non-freezing water are hydrogen bonded to the hydrophilic groups of hydrogels; therefore, the content of nonfreezing water is proportional to the amount of hydrophilic groups in the hydrogels. The content of non-freezing water increases with an increase in the ratio of hydrophilic groups, [77] and decreases with an increase in the ratio of hydrophobic groups.…”

Summary: This paper provides an overview of the latest development in modeling and simulation of volume transition behaviors of hydrogels with models at both macroscopic and molecular levels. Energy conservation law, mass conservation law and momentum conservation law provide good starting points for developing models for hydrogel volume transition. Thermodynamic models, transport models, multiphasic mixture theory and molecular simulation are discussed. Thermodynamic models provide qualitative description of equilibrium volume transition of hydrogels. Both transport models and multiphasic mixture theory can predict transient and equilibrium volume transition of hydrogels. Molecular simulation provides mechanistic understanding of hydrogel volume transition. Several key parameters are summarized for future model development.

“…A neutral hydrogel, a copolymer of hydroxyethyl methacrylate (HEMA) and 2,3-dihydroxypropyl methacrylate (DHPMA) (Wichterle and Lim, 1960), was previously developed for contact lenses. This gel was shown to exhibit an increased resistance to dehydration (Gatesa et al, 2003). The copolymer exhibited high equilibrium water content and good mechanical properties.…”

“…We present here a short account of a more extended water transport study for SCL materials that will be published in full elsewhere [11]. Previous studies report mainly water self-diffusion coefficients [13][14][15][16][17][18] through HEMA SCL or kinetic water uptake data [19][20][21][22]. Reports concerning steady-state water fluxes are rare [12,23].…”
