摘要：
The two-dimensional framework structure of barium-calcium zirconate titanate ceramics was prepared by the freezing orientation method. The ceramic composite material was prepared by filling polyetherimide (PEI) into this structure. The results show that a better two-dimensional structure of ceramic sheets can be obtained when the solid loading of ceramic paste is 30vol%. Among them, TRIS hydrochloride (Tris-HCl) as a dispersant has a better dispersion effect. The filling rate of polymer in ceramic composites is affected by the type of dispersant and the concentration of the filling solution. The permittivity of most composites is below 100, while the relative permittivity of barium zirconate titanate ceramic/polymer composites prepared in this experiment is 446. It is found that Tris-HCl has the best dispersion effect. At this time, when the concentration of polyetherimide/dichloromethane (PEI/DCM) solution is 15wt%, the polymer filling rate of ceramic composites is the highest (18.63%). With the increase of PEI filling rate, the maximum strain value of the ceramic sample increases and the maximum stress value decreases. The in-plane thermal conductivity increases with the increase of temperature. Ensure that it has a certain mechanical strength and improves the permittivity of the material. © 2023 Beijing University of Aeronautics and Astronautics (BUAA). All rights reserved.
