Abstract

Systematic tests have been performed on samples of pressure-sensitive paints(PSPs) with 49 different formulations. Seven porphyrins, two ruthenium complexes, and three aromatic compounds were selectedas a probe molecule. Each compound was deposited onto aluminum plates using silicon polymer, silicon rubber, polystyrene, and silica gel as a binder. These sample plates were tested in a calibration chamber in the pressure range from 10 to 100 kPa and the temperature range of 273 to 333K. In terms of pressure sensitivity, we found that porphyrins were less dependent on binder type than ruthenium complexes and aromatic compounds. Several PSP formulations have been found, which have higher sensitivity than the baseline paint composed of PtOEP and GP197. The temperature sensitivity of those paints, however, is as good as the baseline. Further study will be neededto develop a PSP having lower temperature sensitivity.
