Synthesis and Drug Delivery Application of Thermo- and pH-Sensitive Hydrogels: Poly(β-CD-co-N-Isopropylacrylamide-co-IAM)
Copolymerization of N-isopropylacrylamide (NIPAM), itaconamic acid (IAM; 4-amino-2-methylene-4-oxobutanoic acid) and β-cyclodextrin was investigated in this study. β-cyclodextrin was at first modified by reacting with allyl glycidyl ether to substitute its OH end groups with moieties containing double bonds to facilitate the subsequent radical copolymerization with NIPAM and IAM. It was reporte...
متن کاملSynthesis and Properties of Thermo-Sensitive Hydrogels Based on PVA/Chitosan/PNIPAAm
Thermo-sensitive hydrogels were prepared by graft copolymerization of Polyvenylalcohol and chitosan with N-Isopropylacrylamide via gamma radiation. Characterization of hydrogels such as DSC analysis and swelling and solubility tests in different ratios were investigated. DSC and solubility analysis showed chitosan and PVA and NIPAAm monomer were grafted via gamma radiation successfully. Results...
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 کاملFrontal polymerization synthesis of temperature-sensitive hydrogels.
The study of hydrogels and their response to external environment is of special interest because of their potential as drug delivery systems,1,2 actuators,3 and separation devices.4,5 Temperature-sensitive hydrogels undergo a reversible swellingdeswelling transition with a small change of temperature near the phase transition point.6 A frequently studied thermosensitive hydrogel is based on sol...
متن کاملTemperature sensitive poly(N-t-butylacrylamide-co-acrylamide) hydrogels: synthesis and swelling behavior
A series of temperature sensitive hydrogels was prepared by free-radical crosslinking copolymerization of N-t-butylacrylamide (TBA) and acrylamide in methanol. N,N0-methylenebis(acrylamide) was used as the crosslinker. It was shown that the swelling behavior of the hydrogels can be controlled by changing the amount of TBA units in the network chains. Hydrogels immersed in dimethylsulfoxide (DMS...
