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 β-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/cm3 ). Our results showed that the P(VDF-HFP)-Eu(TTA)3(TPPO)2-BaTiO3 composite nanofibers can be used as multifunctional flexible sensors.
