Title
(EN) INDICATOR MATERIAL COMPRISING A POLYMERIC GEL CARRIER AND POLYMERIC INDICATOR
(FR) MATÉRIAU INDICATEUR COMPRENANT UN SUPPORT DE GEL POLYMÈRE ET UN INDICATEUR POLYMÈRE
Abstract
(EN) The invention relates to a polymeric indicator fixed in a polymeric gel carrier, wherein the polymeric gel carrier comprises a hydrophilic polymer, wherein the polymeric indicator and the hydrophilic polymer are present together in the form of a combined cross-linked hydrogel network fixed by chemical bonds. The invention further relates to a method for preparing a polymeric indicator fixed in a polymeric gel carrier and to a sensor for measuring pH, which comprises the polymeric indicator fixed in a polymeric gel carrier.
(FR) L'invention concerne un indicateur polymère fixé dans un support de gel polymère, le support de gel polymère comprenant un polymère hydrophile, l'indicateur polymère et le polymère hydrophile étant présents ensemble sous la forme d'un réseau d'hydrogel réticulé combiné fixé par des liaisons chimiques. L'invention concerne en outre un procédé de préparation d'un indicateur polymère fixé dans un support de gel polymère et un capteur pour mesurer le pH, qui comprend l'indicateur polymère fixé dans un support de gel polymère.
