Structural Parameters and Swelling Behavior of pH Sensitive Poly(acrylamide-co-acrylic acid) Hydrogels
In the present work, hydrogels based on acrylamide (AAm) and acrylic acid (AAc), crosslinked with N,N’-methylenebisacrylamide (MBAAm) were prepared by free radical polymerization in solution. The effect of initial AAm/AAc mole ratio and nominal crosslinking ratio (moles of crosslinking agent/moles of polymer repeat unit) on the dynamic and equilibrium swelling behaviour of hydrogels was investi...
متن کاملSynthesis of pH Sensitive Hydrogels Based on Poly Vinyl Alcohol and Poly Acrylic Acid
In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...
متن کاملAntimicrobial Loading into and Release from Poly(ethylene glycol)/Poly(acrylic acid) Semiinterpenetrating Hydrogels
Electrostatic interactions within a semiinterpenetrating network (semi-IPN) gel can control the postsynthesis loading, long-term retention, and subsequent release of small-molecule cationic antibiotics. Here, electrostatic charge is introduced into an otherwise neutral gel [poly(ethylene glycol) (PEG)] by physically entrapping high-molecularweight poly(acrylic acid) (PAA). The network structure...

متن کاملPreparation and characterization of pH sensitive crosslinked Linseed polysaccharides-co-acrylic acid/methacrylic acid hydrogels for controlled delivery of ketoprofen
Some pH responsive polymeric matrix of Linseed (Linum usitatissimum), L. hydrogel (LSH) was prepared by free radical polymerization using potassium persulfate (KPS) as an initiator, N,N-methylene bisacrylamide (MBA) as a crosslinker, acrylic acid (AA) and methacrylic acid (MAA) as monomers; while ketoprofen was used as a model drug. Different formulations of LSH-co-AA and LSH-co-MAA were formul...
