| Research Abstract |
Luminescent oxygen sensor dye molecules were dispersed to a construction coating to visualize deteriorated structure and crack on the surface, which corresponded to oxygen quenching. We propose as an advanced structural surface monitoring methodology with nondestructive, real-time, and twodimensional visualization. Crack sensor coatings were prepared via stepwise lamination of gasbarrier layer and oxygen sensor layer. We designed the oxygen sensor layer composed of the oxygen-sensitive 5, 10, 15, 20tetrakis(2, 3, 4, 5, 6pentafluorophenyl) platinumporphyrin dye molecule and high gaspermeative poly(1trimethylsilyl1propyne). Physical damage on the coating was monitored by eye observation or commercially available compact digital camera.
