Problems solved by technology
First of all, due to the high surface energy of inorganic nanoparticles, the aggregation and clustering of particles are caused, and the dispersion in the polymeric organic matrix is not high, so that it cannot be well combined with the polymeric matrix, resulting in a low dielectric constant , high dielectric loss and poor mechanical properties
Secondly, due to the difference in dielectric constant, the electric field distribution in the composite material is not uniform under the induction of the external electric field, which will greatly reduce the breakdown electric field strength of the material.

Abstract
The invention provides an organic-inorganic hybrid composite film material, which comprises inorganic nanoparticles and an organic matter precursor, wherein the surface of the inorganic nanoparticleshas an olefin-based polymer organic shell layer. The present invention further provides a composite material capacitor, which comprises two electrode layers and a dielectric layer formed by using theorganic-inorganic hybrid composite film material and positioned between the two electrode layers. The invention further provides a preparation method of the organic-inorganic hybrid composite film material. According to the present invention, the surface energy of nanoparticles is reduced, the clustering and aggregation of particles in the polymer precursor during the preparation of composite material films is avoided, the compatibility of inorganic matters and organic matter precursors is improved, and the non-uniform distribution of the external electric field induced electric field is reduced, such that the breakdown electric field strength and the energy storage density of the material are improved.
Description
technical field [0001] The invention relates to the technical field of composite films, in particular to an organic-inorganic hybrid composite material, a preparation method and a high-energy-density film capacitor using the composite material. Background technique [0002] Inorganic high dielectric material nanoparticles (such as BaTiO 3 ,TiO 2 and PZT, etc.) are introduced into organic polymers to form composite materials, which is one of the methods to obtain high energy density film capacitor materials. The composite material has the advantages of high dielectric of inorganic particles and high breakdown electric field of polymer matrix. However, there are still some problems to be solved in terms of application. First of all, due to the high surface energy of inorganic nanoparticles, the aggregation and clustering of particles are caused, and the dispersion in the polymeric organic matrix is not high, so that it cannot be well combined with the polymeric matrix, re...
