Smart hydrogels containing 2,2,6,6-tetramethylpiperidinoxy methacrylate (TEMPO) and N-isopropylacrylamide (NIPAM) that undergo reversible redox behavior are prepared and investigated. Several polymer networks are first prepared by free-radical copolymerization of varying amounts of TEMPO, NIPAM, and a crosslinker (diethylene glycol diacrylate) and subsequently swelled with water to lead to hydrogels. In order to investigate the effects of the redox activity of TEMPO units and of the lower critical solution temperature of NIPAM on the hydrogel properties, a study of the swelling ratio of the polymer networks in distilled water at different temperatures is performed for the two forms of TEMPO, the reduced (TEMPO) and oxidized (TEMPO+) one. Moreover, the rheol. properties are also measured for both hydrogel forms. Finally, the encapsulation abilities of the oxidized hydrogels are demonstrated via electrostatic interactions between pos. charged TEMPO+ units and neg. charged guest mols., supporting future application of our system in the biomedical and environmental fields. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Electric Literature of C10H14O5).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Electric Literature of C10H14O5
