E. Puklin et al., Ideality of pressure-sensitive paint. I. Platinum tetra(pentafluorophenyl)porphine in fluoroacrylic polymer, J APPL POLY, 77(13), 2000, pp. 2795-2804
The pressure sensitive paint (PSP) properties of a fluoroacrylic polymer, F
IB, with the luminophor platinum tetra(pentafluorophenyl)porphine (PtTFPP)
are presented. This paint forms a hard coating that displays Stern-Volmer p
lots with a high dynamic range (similar to 0.9) [defined as (I-vac - I-atm)
/I-vac], good photostability, a response time of less than 1 s and a relati
vely low temperature dependence (similar to 0.6% per degree). The temperatu
re dependence is low because FIB has a unusually low activation energy for
the diffusion of oxygen. Pressure and temperature affect intensity independ
ently making this PSP "ideal." The basecoat affects the functionality of th
e PSP it underlies, and the optimal basecoat used to date also includes the
FIB polymer. The synthesis of the FIB polymer is a copolymerization that o
ccurs in one step with a peroxide initiator. Annealing the painted model ab
ove T-g = 70 degrees C procures adhesion and ideality. (C) 2000 John Wiley
