Sensormembran zur Bestimmung von chemischen Stoffkonzentrationen und Verfahren zu deren Herstellung

摘要

The invention relates to a sensor membrane for determining oxygen concentrations and to a method for the production of said membrane, wherein an indicator is contained in an oxygen-permeable polymer matrix, the optical and physical-chemical properties of which may be influenced by the corresponding analytes. Based on disadvantages encountered with existing sensor membranes, the invention aims at providing a sensor membrane that is stable with respect to temperature and shape and that can be easily and flexibly produced. According to the invention, this is achieved in that the polymer matrix containing the optical oxygen indicator is formed by a polymer with sulfur, preferably in the main chain, more preferably with sulfide and/or sulphone functionalities in the main chain.
