Rare earth doped BCZT piezoelectric nanofiber as well as preparation method and application thereof
The invention provides a rare earth doped BCZT nanofiber as well as a preparation method and application thereof. The chemical formula of the rare earth doped BCZT nanofiber provided by the invention is Ba0.85-xMxCa0.15(Zr0.1Ti0.9)O3, M is a rare earth element, and x is greater than or equal to 0.01 and less than or equal to 0.05; the length of the rare earth doped BCZT nanofiber is 5-10 mum, and the radial width is 50-200 nm. A sol-gel method is combined with electrostatic spinning for preparation, atomic-level dispersion and uniform doping of doping elements are achieved, crystal continuity of rare earth doped BCZT nanofibers is good, piezoelectric performance and dielectric performance of BCZT ceramic are effectively improved, and dielectric loss is reduced. The rare earth doped BCZT nanofiber can be directly compounded with a flexible high polymer material to prepare a piezoelectric nano-generator, and is effectively applied to the fields of nano-electronic devices such as biomedicine, wireless sensing and flexible devices.
