Electroactive and photoluminescence of electrospun P(VDF-HFP) composite nanofibers with Eu3+ complex and BaTiO3 nanoparticles

Multi-functional polymer nanofiber films have various applications in soft electric devices. In this work, electroactive and photoluminescence of electrospun polyvinylidene fluoride hexafluoropropylene (P(VDF-HFP)) composite nanofibers were achieved by adding Eu(TTA)(3)(TPPO)(2 )and BaTiO3 fillers. The effects of Eu (TTA)(3)(TPPO)(2) and BaTiO3 fillers on the crystal structure, mechanical properties, ferroelectric properties, and fluorescent properties of P(VDF-HFP) nanofibers were investigated. In contrast with adding alone Eu (TTA)(3)(TPPO)(2) or BaTiO3 filler, the beta-crystal content, ferroelectric properties and fluorescent properties of P (VDF-HFP) nanofibers were significantly improved by mixture filler of Eu(TTA)(3)(TPPO)(2) and BaTiO3 owing to coordination effect. And, the sandwich-structured polymerurethane PU/P(VDF-HFP)-Eu(TTA)(3)(TPPO)(2)- BaTiO3/PU device presented high low pressure sensitivity (0.49 kPa(-1)) and high energy density (30.45 mJ/ cm(3)). Our results showed that the P(VDF-HFP)-Eu(TTA)(3)(TPPO)(2)-BaTiO3 composite nanofibers can be used as multifunctional flexible sensors.
