Problems solved by technology

However, this method of adjusting the dielectric properties of the composite material through the addition of ceramics is still limited to the improvement of the dielectric constant of the composite material (general dielectric constant <50), and the introduction of a large amount of fillers will inevitably lead to a large number of defects, thereby reducing the material. compressive strength
Second, adding a conductive phase filler to the polymer matrix can obtain a higher dielectric constant by using the percolation effect, but the dielectric loss also rises sharply with the increase of the filler filling amount, so it is generally not of practical value

Abstract

The invention discloses a heterogeneous particle-carried inorganic filler and a preparation method thereof. The inorganic filler is prepared from an inorganic material and organic acid metal salt which serve as raw materials; the mass ratio of the inorganic material to the organic acid metal salt is (1-10):1. The preparation method comprises the following steps: dissolving the organic acid metal salt in a solvent to form a solution, adding the inorganic material for mixing and stirring, evaporating the solvent, and then heating the mixture to thermally crack the organic acid metal salt on the surface of the inorganic material, so as to form the heterogeneous particle-carried inorganic filler. Compared with a conventional ceramic filler and a conventional conductive phase filler, the heterogeneous particle-carried inorganic filler disclosed by the invention and the conductive phase filler have the advantages that the inorganic filler of the structure can substantially increase the dielectric constant of a polymer composite material and also can guarantee relatively low dielectric loss.
