Abstract:
A method for preparing a piezoelectric film includes: coating a solution containing a piezoelectric polymer and a solvent on a substrate to obtain a film, wherein the piezoelectric polymer is a copolymer of vinylidene fluoride and trifluoroethylene; and annealing the film at a temperature ranging from 122° C. to 133° C., to obtain the piezoelectric film.
