Natural polymer-based electroconductive hydrogels via thiol-ene click reaction = Natural polymer-based electroconductive hydrogels via thiol-ene click reaction

다국어 초록 (Multilingual Abstract)

Thiol-ene reactions have been widely used because they have the characteristics of “click reactions”, which are fast and high-yielding without side reactions. The hydrothiolation reactions proceed either by a radical pathway or catalytic pathway. Although there are differences of reactivity and reaction mechanism, ene species (i.e. terminal alkene, norbornene) and thiol species have a wide range of substrate scope to proceed thiol-ene reaction. In this study, alkene-functionalized alginates were converted to hydrogels via UV-mediated thiol-ene reaction. For furnishing electroconductivity, the alginates were blended with conducting polymers. The synthesized hydrogels were characterized by rheology and electrochemical spectroscopy. We tested the electoconductivity of the hydrogels when divalent ions are bound to alginate, since the microstructure of the hydrogel can be changed upon binding of divalent ions.
