Preparation method of full spin-coating type flexible hybrid piezoelectric generator

The invention relates to the technical field of nanometer generator preparation, in particular to a preparation method of a full spin-coating type flexible hybrid piezoelectric generator. The preparation method comprises the steps that firstly, surface treatment is conducted on nanometer zinc oxide with a dispersing agent and a surface modifying agent so as to improve the compatibility between a base material and nanometer filler, improve the nucleation capacity of the nanometer zinc oxide and obtain a high-crystallinity composite film; secondly, a full spin-coating technology is provided, wherein in the first spin-coating process, the film suffers from shear stress, so that polyvinylidene fluoride-trifluoroethylene molecular chains are induced to be directionally aligned, and the formation of a beta phase is facilitated; in the second spin-coating process, spin-coated conductive macromolecular poly(3,4-ethylenedioxythiophene): polystyrene sulfonate serves as a top electrode, the problem about interlayer matc
