PHOTORESPONSIVE HYDROGEL CAPABLE OF CONTROLLING EMISSION OF AQUEOUS TARGET MATERIAL BY PHOTO-IRRADIATION BY USING COUMARIN, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A photoresponsive hydrogel is provided to control the emission of light under 260 nm by reducing the cross-linking density of hydrogel by irradiating with a light in 260 nm or less, or increasing the cross-linked density by irradiating with a light in 310 nm or more.;CONSTITUTION: A photoresponsive hydrogel is formed by photocrosslinking an aqueous polymer combined with photocrosslinking the water-aqueous polymer combined with a coumarin derivative, and can control the emission of water-soluble target material by photo-irradiation. A manufacturing method of the photosensitive hydrogel comprises: a step of binding a coumarin derivative to an aqueous polymer; a step of manufacturing hydrogel by photo-crosslinking an aqueous polymer solution combined with a coumarin derivative, and a step of mounting a hydrophilic target material to the hydrogel.;COPYRIGHT KIPO 2013
