Probe molecules of Eu (MAA)₃Phen, Eu (Sal)₃Phen and Eu (CA)₃Phen were prepared by using europium oxide (Eu₂O₃), methacrylate (MAA), salicylic acid (HSal), cinnamic acid (HCA) and phenanthroline (Phen).A series of temperature sensitive paints (TSPs) were obtained by the polymerization of different probe molecules, methyl methacrylate (MMA) and the initiator of benzoyl peroxide (BPO).The structure, morphology, luminescence property of probe molecules and the temperature quenching property of TSPs were characterized by infrared spectrometer, fluorescence spectrometer and scanning electron microscopy.The effect of different ligands on the luminescence property of probe molecules and the temperature quenching property of TSPs were studied.It is indicated that the fluorescence intensity of Eu (MAA)₃Phen is obviously higher than that of Eu (Sal)₃Phen or Eu (CA)₃Phen, and the temperature quenching properties of the three TSPs are good.The temperature sensitivity of Eu (MAA)₃Phen/PMMA and Eu (CA)₃Phen/PMMA is higher in 55~65℃.However, the temperature sensitivity of Eu (Sal)₃Phen/PMMA is higher in 35~45℃.That is to say, different TSPs can be used in different temperature ranges.
