초록 Temperature and ionic strength sensitive hydrogels play an important role in the
application of pharmacy, medicine and separation operations in biotechnology. The most
important thermodynamic property of gel is the degree of swelling for application.
Thermodynamically, swelling behaviors of nonionic hydrogels were interpreted by the
polymer-solvent mixing free energy and elastic free energy.
In this study, to successful prediction of nonionic hydrogels, we combined the Modified
Perturbed Hard Sphere Model (MPHSC) and Flory and Erman‘s theory of elasticity.
We used Modified PHSC developed by Chapman’s bonding term as the reference term
and van der Waals attractive term as the perturbation. Our proposed model shows good
agreements with experimental PVT data water and gel swelling data.
