Abstract: PROBLEM TO BE SOLVED: To obtain a functional polymer having a pressure-sensitive coloring matter, pressure-sensitive paint and pressure-sensitive element which can prevent deterioration of photoresponse due to aggregation of coloring matter when an organic solvent is evaporated and produce a sensor thin film having uniform characteristics. SOLUTION: Since an oxygen extinction coloring matter group included in a pressure-sensitive coloring matter directly bonds with an organic polymer compound having a trimethylsilyl group by a covalent bond, when the solvent is evaporated, the coloring matter cannot form aggregation because molecules of the coloring matter are fixed with the polymer. Therefore, deterioration of photoresponse due to aggregation of coloring matter when an organic solvent is evaporated can be prevented, which is a problem when applying a conventional mix-type pressure-sensitive paint. By mixing a functional polymer with a solvent to prepare a pressure-sensitive paint, a sensor thin film having uniform characteristics can be formed with spray coating or spread coating. In addition, by dissolving a single component into an adequate solvent, a coating liquid suitable for spray coating and spread coating can be obtained with high repeatability. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To obtain a highly functional pressure-sensitive paint capable of easily forming an oxygen sensitive film regardless of the material of a specimen while having rapid response against fluctuations in pressure and high oxygen sensitivity not lowered even by the temperature of liquid nitrogen. SOLUTION: By using poly (TMSP) as a binder of a light exciting substance, a paint mixed with the light exciting substance becomes the extremely excellent highly functional pressure-sensitive paint which has both of high pressure sensitivity and low temperature sensitivity by the high oxygen transmissivity of the binder and does not lose oxygen sensitivity even at the temperature of liquid nitrogen and has good response against fluctuations in pressure and can be subjected to spray coating and can be applied regardless of the material and shape of a specimen.

Abstract: The present invention provides an optical oxygen concentration measurement method and optical oxygen concentration measuring sensor wherein a light-absorbing dye-molecule layer whose absorption spectrum varies depending on the bonding with oxygen molecules is combined with a light-emitting layer, and the oxygen concentration of the ambient fluid can be measured. The light-absorbing layer 4 laminated to an oxygen-quenching light-emitting layer 3 is a film comprising a cobalt-porphyrin complex (CoP) or other light-absorbing dye molecule 7 whose absorption spectrum varies depending on the bonding with oxygen molecules. When the degree of overlap with the light emission spectrum or excitation (absorption) spectrum of the light-emitting layer 3 varies as a result of a variation in the absorption spectrum possessed by the light-absorbing layer 4, the light intensity of output light varies in accordance with the degree of overlap, and the oxygen concentration of the ambient fluid can be measured. These measurement method and measuring sensor can be applied not only to optical fiber sensors, but also to wind tunnel experiments and the like as pressure-sensitive paints.

Abstract: An oxygen-quenching luminophore constituting part of a pressure-sensitive luminophore is directly bonded by a covalent bond to an organic polymer compound having trimethylsilyl groups, so the luminophore molecules are retained in the polymer and free aggregation is inhibited when the organic solvent is evaporated. It is therefore possible to prevent light response from being reduced by the aggregation of the luminophore molecules during evaporation of the organic solvent, which is a drawback of forming films from conventional mixed-type pressure-sensitive paints. A thin-film sensor with uniform characteristics can be formed by spraying or application from a pressure-sensitive paint obtained by mixing a functional polymer with a solvent. In addition, a coating solution that has high reproducibility and is suitable for spraying or application can be obtained merely by dissolving the functional polymer as a single component in a suitable solvent. It is possible to obtain a functional polymer, a pressure-sensitive paint, and a pressure-sensitive element in which a reduction in light response due to luminophore aggregation can be prevented, and a thin sensor film having uniform characteristics can be formed, even when the organic solvent has evaporated.
