Cross-linked gas permeable membrane of a cured perfluorinated urethane polymer, and optical gas sensors fabricated therewith

摘要

An optical sensor is provided for measuring dissolved gases such as O2 or CO2 in a fluid sample. The sensor is formulated so as to contain a gas permeable membrane of a cured perfluorinated urethane polymer and, incorporated therein, a gas-sensitive indicator component. Methods for making and using the membrane and sensor are provided as well.
