イオン液体をバインダとして用いた感圧塗料の研究

抄録

The properties of Pressure-Sensitive Paint (PSP) with an ionic liquid as a binder have been investigated. An ionic liquid is a salt in the liquid state at room temperatures. The aggregation of pressure-sensitive dye often occurs in the polymer binder of PSP and gives an influence on the PSP properties such as pressure sensitivity and luminescence intensity. It is expected the ionic liquid as a binder avoids the aggregation of the dye and enhance the PSP properties. In this study, we developed the PSP with the ionic liquid and pressure and temperature sensitivities were measured in a calibration chamber. The developed PSP showed a high pressure sensitivity of 0.9%/kPa and a high temperature sensitivity of 2%/°C.
