Pressure-sensitive paints (PSPs) have been demonstrated to be very important for aerodynamics research. In order to improve the pressure sensitivity and adhesion ability of PSP, herein, a series of fluorine-containing copolymers compositing of an oxygen and pressure-responsive probe derived from platinum(II)-5,10,15,20-tetrakis-(2,3,4,5,6-pentafluorophenyl)-porphyrin (PtTFPP) named as poly[(tBs)(a)-co-(TFEM)(b)-co-(PtTFPP-1MA)(c)] were synthesized and investigated as PSPs. These PSPs were constructed with different fluorine ratios for the investigation of the effect of fluorine contents on PSPs. Especially, PSP (F-0.33) with the trifluoroethyl methacrylate (TFEM) molar ratio of 33% in the copolymers could adhere well to the surface of an aircraft model. F-0.33 showed high oxygen sensitivity (I-0/I-100 = 32.87), reasonable response time to oxygen (44 s), high pressure sensitivity (S-P = 0.75%/kPa at 20?) and low temperature response (S-T = -0.77%/? at 100 kPa). F-0.33 was further sprayed on the surface of a delta wing of an aircraft model and its pressure response was verified in a wind tunnel. The data from F-0.33 film at the same wind speed and position were close to the pressure data measured by using traditional method using open pressure holes, showing the potential application of these PSPs.
