Equilibrium swelling behavior of pH- and temperature-sensitive poly(N-vinyl 2-pyrrolidone-g-citric acid) polyelectrolyte hydrogels

Evaluation of Different Concentrations of Antimicrobial Quaternary Polymers on the Behavior of Gelatin- and Starch-Based Films

“…With the incorporation of the polymer, as its concentration in the blend increased, the number of intermolecular interactions increased, causing the material to lose elasticity by reducing the spaces between the polymeric chains. This makes the material less flexible and, therefore, decreases its ability to deform and swell [ 48 , 49 ].…”

Swelling and Dissolution of β-Lactoglobulin Gels in Alkali

“…Swelling of β Lg Gels at Different pH's and Ionic Strengths. Swelling studies on simple polyelectrolyte hydrogels , have shown that the plot of Q with pH follows the hydrogen ion equilibrium curve of the polymer. Hence, as the number of fixed charges increases due to the ionization of the different groups, Q also increases.…”

Preparation of novel tissue acidosis-responsive chitosan drug nanoparticles: Characterization and in vitro release properties of Ca2+ channel blocker nimodipine drug molecules

“…Much attention has been directed in recent years to polyelectrolyte hydrogels that show different swelling behaviors in response to small variation in solution conditions such as temperature and pH (Caykara et al, 2000;Nonaka et al, 1998;Lee et al, 1996). These hydrogels are used in variety of novel applications, including controlled drug delivery (Horiike et al, 2000), immobilized enzyme system (Putman & Kopecek, 1995) and separation processes (Karadag et al, 1995).…”
