Temperature-Compensated Pressure-Sensitive Paint Containing a Bichromophoric Luminophore

摘要

The effort that has been undertaken during this Phase I STTR program will enable NanoSonic and their academic partner at the University of Dayton to readily move toward commercialization of a sensor paint during Phase II. A bichromophoric compound containing a pressure-sensitive chromophore and a temperature-sensitive chromophore has been synthesized and formulated into a paint. The luminescent intensity response of the temperature sensor was characterized by fluorescence spectroscopy and was found to be linear in the specified temperature range. The luminescence intensity from the pressure sensor emission peak was found to be temperature independent. In addition, communications with Northrop Grumman during Phase I have lead to a partnership for independent testing of the sensor paint in a development wind tunnel.
