Radiation-sensitive composition and use thereof in the preparation of electrochemical ion sensors

摘要

Radiation-sensitive compositions are disclosed of a type suitable for preparing ion-sensitive membranes for electrochemical ion sensors. The compositions are comprised of a radiation-crosslinkable polymer comprising recurring units having an ionophore group and recurring units having a crosslinkable group. An electrochemical sensor may be prepared by coating a surface of the sensor with the radiation-sensitive composition, exposing the composition to activating radiation to produce crosslinking in areas where the membrane is required and removing any non-exposed portions of the composition.
