| 英文摘要 | Based on luminescence quenching of chromophoric probes in oxygen permeable polymer matrix, pressure sensitive paint (PSP) and its devices have been developed as a kind of functional materials in recent years. The pressure sensitivity of PSP not only depends on the probe molecules, but also on the polymer matrix. In this work,tetrakis(pentafluorophenyl) porphyrin platinum (PtTFPP), as a luminescent probe,was composed with polydimethylsiloxane (PDMS), polymethylphenylsiloxane (PMPS), polymethyltrifluoropropylsiloxane (PFS) and trifluorochloroethylene-vinyl acetate copolymer (PFC) respectively, and then their luminescence quenching behaviors were measured at an excitation of lambda = 365 nm with various oxygen concentrations from 0% to 100%. The ratio I-0/I-100 is used as oxygen sensitivity of PSP films, where I-0 and I-100 represent the fluorescence intensities from films exposed to 100% nitrogen and 100% oxygen, respectively. The I-0/I-100 values of the PtTFPP-based films are evaluated. It is found that the plots of I-0/I versus [O-2] with identical Ksv are obtained and a two-site model fits the experiment data very well for the PtTFPP/polymer systems, except PtTFPP/PFC films. The values of I-0/I-100 and K-sv for such materials increased with increasing the oxygen permeability of the polymer matrix, i. e. PDMS > PMPS > PFS > PFC, which is identical with theoretical reasoning. Therefore it could be concluded that the oxygen quenching for the PSP materials in this work showed a diffusion-controlled mechanism. |
