Enhanced output performance of NaNbO3-based tribo-materials modified with NiFe2O4 particles

The NaNbO 3 –SrSnO 3 –Bi 0.5 Na 0.5 TiO 3 (NN–SS–BNT) ferroelectrics were synthesized by a solid-state reaction process, and the effect of NN–SS–BNT and/or NiFe 2 O 4 (NF) particles as fillers on the output property of polydimethylsiloxane (PDMS) films was investigated. It was found that the 0.8(NN–SS)–0.2BNT ceramic possessed a highest dielectric constant value of 654 at 10 kHz in this research. The above inorganic particles could effectively enhance the electrical output values of PDMS , and especially the output voltage of NN–SS–BNT/NF/PDMS film was significantly higher than that of the PDMS film. The voltage value of NN–SS–BNT/NF/PDMS film with weight ratio of 10/5/85 was measured approximately 335 V.
