HYDROGEL, PREPARATION METHOD THEREOF, AND pH SENSOR COMPRISING THE SAME |
| abstract |
A method for preparing a hydrogel that reversibly changes color depending on pH includes: (S 10 ) dissolving a carboxyl group-containing polysaccharide in buffer to obtain a polysaccharide solution; (S 20 ) adding a cross-linker solution composed of a mixture of an organic solvent and a cross-linker to the polysaccharide solution; (S 30 ) adding, to the cross-linker-containing polysaccharide solution resulting from step (S 20 ), an organic solution composed of a mixture of an organic solvent and a first organic compound containing an aromatic functional group having at least one hydroxyl group bonded thereto, to form a mixture solution, and allowing the mixture solution to react; (S 40 ) obtaining a polymer complex from the reaction mixture resulting from step (S 30 ); and (S 50 ) mixing the polymer complex from step (S 40 ) with an organic dye comprising a second organic compound containing an aromatic functional group having at least one hydroxyl group bonded thereto. |
