Ideality of pressure‐sensitive paint. I. Platinum tetra(pentafluorophenyl)porphine in fluoroacrylic polymer

Ideality of pressure-sensitive paint. II. Effect of annealing on the temperature dependence of the luminescence

“…The PSP formulation used in this study was comprised of a platinum tetra(pentafluorophenyl)-porphine (PtTFPP) sensor, purchased from Porphyrin Products (Logan, UT), dissolved in FIB. 23 The paint was sprayed from p-chlorotrifluorotoluene (which was obtained under the trade name Oxsol-100 made by Occidental Chemical Corp., Dallas, TX) on clean aluminum coupons (2.5 ϫ 2.5 cm). Samples with a thickness of about 12-15 m and an average smoothness (measured with a Surtronic 10 profilometer) of 1 m were generally obtained.…”

“…In an earlier article, 23 which we consider Paper I of this series on PSP, we describe the synthesis of the polymer FIB made from hexafluoroisopropyl and heptafluoro-n-butyl methacrylate and show that it is a nearly ideal PSP, in that pressure and temperature dependencies are independent. Because the present article concerns the requirements for the parameters of the various decay rates necessary to ideal behavior, we here review the concept of an ideal PSP.…”

Synthesis and properties of novel random copolymers made from N-acryloyl piperazine-based monomers and fluoroalkylmethacrylates

“…Fluoroalkylacrylic polymers attract interest as polymer matrixes for pressuresensitive paint (PSP) [1][2][3][4]. The pressure fields on the surfaces of the machine elements are visualized by luminescence quenching of organic luminophore & Inna K. Shundrina ishund@nioch.nsc.ru dissolved in the polymer matrix due to interaction between the luminophore and oxygen [5][6][7][8].…”

“…The polymer has to be highly permeable to oxygen, stable towards oxidation and UV destruction. One of the requirements to the polymer matrix is that the oxygen movement in the polymer should be as free as possible with the diffusion activation energy close to zero in a wide temperature range [1]. In this case, the luminescence quenching in the polymer has weak temperature dependence and is mainly determined by pressure.…”

Ideality of pressure-sensitive paint. III. Effect of the base-coat permeability on the luminescence behavior of the sensing layer

“…20 In this article, we report the results concerning the effect of different base coats on the ideality of a PSP, which consists of platinum tetra(pentafluorophenyl)porphine (PtTFPP) dissolved in FIB, a copolymer of hexafluoroisopropyl and heptafluoron-butyl methacrylate. 21 The effect of the pigment volume concentration (PVC) is also studied and related to the ideality of the PSP. Other properties such as response time and photodegradation are also studied.…”
