A photostable bi-luminophore pressure-sensitive paint measurement system developed with mesoporous silica nanoparticles.

ABSTRACT

The accurate and high-resolution measurement of surface pressure is achieved by a pressure/ temperature-sensitive composite paint (bi-PSP), whereas the pressure-sensitive dye photodegraded the temperature sensitive dye in close arrangement of both dyes. In the present study, an attempt was made to synthesize a homogeneous bi-PSP membrane without light-induced degradation of the dye using mesoporous silica. Mesoporous silica as a molecular sieve was the separation of pressure- and temperature-sensitive dyes. Both achievement of control of photodegradation in temperature-sensitive paints with molecule-screening capacity and macroscopically uniform placement of insoluble pigments in the respective solvent, was accomplished using the mesoporous silica nanoparticles in a compound PSP.
