这篇文章报道了退火对压敏漆（PSP）的影响，该压敏漆由在称为FIB的氟丙烯酸聚合物中的铂四（五氟苯基）卟啉（PtTFPP）组成（Puklin，E.; Carlson，W. B.; Gouin，S.; Costin，C.;绿色，E.;波诺马列夫，S。; Tanji，H.; Gouterman，M. J Appl Polym Sci 2000，77，2795）。将在150°C、75°C下退火、通过热风枪退火并在室温下干燥的样品与未退火的样品进行比较。研究了发光强度和寿命的温度依赖性，并将其作为压力和温度的函数，并与Arcourius和Stern-Volmer方程拟合。我们发现，在降低温度依赖性和获得理想的PSP，理想的意思是独立的压力和温度对涂料的发光性能的影响，在Tg以上的加热比在室温下干燥更重要。通过降低氧扩散的活化能来实现理想化，推测是通过聚合物网络的松弛。结果表明，理想的行为只发生在一个有限的温度区域。该范围对于FIB中的PtTFPP比对于聚二甲基硅氧烷（PDMS）（另一种常见PSP制剂）中的钌红菲咯啉更有用。© 2000 John Wiley & Sons，Inc.应用聚合物科学杂志77：2805-2814，2000
This article reports the effect of annealing on a pressure-sensitive paint (PSP) consisting of platinum tetra(pentafluorophenyl)porphine (PtTFPP) in a fluoroacrylic polymer called FIB (Puklin, E.; Carlson, W. B.; Gouin, S.; Costin, C.; Green, E.; Ponomarev, S.; Tanji, H.; Gouterman, M. J Appl Polym Sci 2000, 77, 2795). Samples annealed at 150°C, 75°C, annealed by a heat gun, and dried at room temperature are compared to nonannealed samples. Temperature dependences of luminescence intensity and lifetime are studied as a function and pressure and temperature and fit with Arrhenius and Stern–Volmer equations. We find that heating above Tg is more important than drying at room temperature in lowering the temperature dependence and obtaining ideal PSP, ideal meaning independent effect of pressure and temperature on luminescence properties of the paint. Ideality is achieved by lowering the activation energy for oxygen diffusion, presumably by relaxation of the polymer network. It is shown that ideal behavior occurs only over a limited temperature region. This range is more useful for PtTFPP in FIB than for ruthenium bathophenanthroline in polydimethylsiloxane (PDMS), another common PSP formulation. © 2000 John Wiley & Sons, Inc.
