抄録

Pressure sensitive paint (PSP) technique is based on the interaction of oxygen molecules with luminescent molecules, and it seems suitable for analyses of high Knudsen number flows which require diagnostic tools in the molecular level. However, application of the PSP technique to micro-devices is still very difficult because of the thickness of PSP layers of the order of microns and the aggregation of luminescent molecules caused by the "painting" methods. To resolve the problems of ordinary PSPs mentioned above, we adopt the Langmuir-Blodgett (LB) method to fabricate pressure sensitive molecular films (PSMFs) having nanometer order thickness. The fundamental properties of the PSMFs such as the pressure sensitivity and the surface roughness are examined, to evaluate the feasibility of the PSMF technique for pressure measurement around micro-devices. A PSMF based on palladium (II) mesoporphyrin IX shows high pressure sensitivity in low pressure regime, while a PSMF based on platinum (II) mesoporphyrin IX is optimum for atmospheric pressure. It is also clarified that the PSMFs do not degrade the roughness of solid surfaces. The results indicate the feasibility of the PSMF technique for pressure measurement in high Knudsen number flows such as micro flows.
