Title
(EN) HYDROGEL-BASED PH SENSORS FOR WET ENVIRONMENTS
(FR) CAPTEURS DE PH À BASE D'HYDROGEL POUR DES ENVIRONNEMENTS HUMIDES
Abstract
(EN)
Provided herein is a hydrogel for pH sensing, comprising poly(3,4- ethylenedioxythiophene) doped with poly(styrenesulfonate) ("PEDOT:PSS") dispersed in a polymer matrix (PM), wherein the PEDOT:PSS and PM are present in a ratio such that the hydrogel is stable in aqueous solution. There is also provided hydrogel compositions comprising PEDGT:PSS; a polymer matrix (PM); and a solvent, wherein the PEDOT:PSS and PM are present in the composition in a ratio such that the composition dries to form a hydrogel that is stable in aqueous solution. Methods of making these hydrogels and hydrogel compositions, as well as uses of these hydrogels and hydrogel compositions as or in pH sensing devices are also described.

L'invention concerne un hydrogel pour la détection du pH, comprenant un poly(3,4-éthylènedioxythiophène) dopé par du poly(styrène sulfonate) ("PEDOT:PSS") en dispersion dans une matrice polymère (PM), le PEDOT:PSS et le PM étant présents selon un rapport tel que l'hydrogel soit stable en solution aqueuse. L'invention concerne également des compositions d'hydrogel comprenant du PEDGT:PSS ; une matrice polymère (PM) ; et un solvant, le PEDOT:PSS et le PM étant présents dans la composition selon un rapport tel que la composition sèche pour former un hydrogel qui est stable en solution aqueuse. L'invention concerne également des procédés de fabrication de ces hydrogels et de ces compositions d'hydrogel, ainsi que des utilisations de ces hydrogels et de ces compositions d'hydrogel en tant que dispositifs détecteurs de pH ou dans ces derniers.
