아조 화합물을 함유한 광감응형 스마트 하이드로겔의 제조및 특성

Abstract

On this study, we synthesized photo responsive smart hydrogel using method of photopolymerization. Photoisomerization of synthesized azo-compoumd was detected by UV-vis spectroscopy. Effect of azo-compound was converted trans into cis and cis into trans by way of dose of 365nm or 400~500nm respectively, and these transformations were showed. We studied that when using hydrogel to disperse drug, drug dispersion was showed differently according to physical of chemical bonding of azo-compound which is inside of hydrogel. And added hydrogel in azo-vinylether has excellent properties. The difference in switching phenomenon of azo-compound has showed different aspect because of side chain in azobenzene. Switching phenomenon of azo-compound in hydrogel was possibly applied to not only DDS (drug delivery system) but also artificial muscle. Existing artificial muscle system was progressed using a reversible reaction changes by voltage. but we expect there is potential possibility of photo responsive hydrogel is reacted by light.
