This application discloses a method for preparing a liquid crystal polymer composite film and the liquid crystal polymer composite film itself. The preparation method includes: dissolving soluble liquid crystal polymer particles in a first solvent and stirring to obtain a soluble liquid crystal polymer solution; mixing the soluble liquid crystal polymer solution, filler micropowder, and additives to obtain a first mixture; dispersing and degassing the first mixture to obtain a slurry; the filler micropowder includes at least one of titanium dioxide, barium titanate, barium zirconate, lead titanate, calcium zirconate, calcium titanate, carbon nanotubes, graphene oxide, and reduced graphene; coating the slurry onto a substrate to form a wet film on the substrate; drying and curing the wet film to obtain a first film; and peeling the first film off the substrate to obtain the liquid crystal polymer composite film. In this application, the filler micropowder and the liquid crystal polymer matrix work synergistically to achieve a high dielectric constant while maintaining low loss. It is also less prone to breakage or deformation under external forces.

A calcium titanate-based dielectric material with high energy storage performance was designed. The chemical formula of this material is Ca. 1‑x Dy x (Ti 1‑y Hf y ) 1‑x / 4 O3-z mol%M, where x=0.005~0.05, y=0.1~0.2, z=0~2, and M is MnO2 or BaCu(B2O5). It is prepared using solid-state reaction and tape casting methods. This invention, based on calcium titanate-based ceramics with high breakdown field strength, employs a series of strategies to improve energy storage performance, including element substitution, doping with sintering aids, and process improvement: partial substitution of Hf elements at the B site increases the band gap; doping with sintering aids improves grain density, both of which enhance the breakdown field strength; the addition of rare earth element Dy enhances the polarization response by introducing defect dipoles; the non-stoichiometric design reduces oxygen vacancy compensation, thereby increasing resistivity; and the tape casting method improves ceramic density and grain uniformity. The final prepared calcium titanate-based energy storage medium ceramic material exhibits good energy storage performance, with Ca... 0.995 Dy 0.005 (Ti 0.9 Hf 0.1 ) 0.99875 The best energy storage performance was achieved in O3-0.5 mol% BaCu(B2O5) ceramics, with a breakdown field strength of 101.90 kV / mm and an effective energy storage density of 10.22 J / cm³. 3 .
