摘要：
A lead-free barium titanate(BaTiO3, BTO)/graphene Oxide(GO)/Polydimethylsiloxane(PDMS) three-phase high-performance piezoelectric composite film is prepared. GO is used as a carbon-based conductive phase material to form micro-capacitors in the ferroelectric composite film, which improves the piezoelectric performance of the composite films. When the GO concentration is 0.6 wt%, the electrical and ferroelectric properties of the composite films are mea⁃ sured. The experimental results show that the prepared BTO/GO/PDMS composite film has a dielectric constant of 185 and a residual polarization of 13.47 μC per square centimeter (higher than the pure phase BTO/PDMS composite film). The maximum open circuit voltage of the BTO/GO/PDMS nanocomposite film generator is 2.78 times that of the BTO/PDMS nanocomposite film generator. Based on the above research results, this lead-free green-friendly flexible composite material has great application prospects in vibration energy harvesting and integrated ferroelectric devices. © 2022 Chinese Institute of Electronics.
