Oxygen sensing membranes and methods of making same |
摘要 |
A polymeric sensing membrane having a Stern-Volmer constant within a pre-determined range of Stern-Volmer constants. The membrane includes a polymeric material having a fluorescent dye molecule dispersed therein. The dye molecule is capable of having its fluorescence collisionally quenched by a gas to be detected by the membrane. In one embodiment, the membrane includes a fluorescent dye molecule which has a relaxation time and a polymeric material having a permeability within a range of permeabilities defined by a mathematical function of the pre-determined range of Stern-Volmer constants. In another embodiment, the membrane includes a polymeric having a permeability and a fluorescent dye molecule having a relaxation time within a range of relaxation times defined by a mathematical function of the pre-determined range of Stern-Volmer constants.
