Modified barium titanate foam ceramic/thermosetting resin composites and preparation method thereof

In a method of preparing a modified barium titanate foam ceramic/thermosetting resin composite material, an organic additive is used as an auxiliary; deionized water is used as a solvent; nanometer barium titanate is used as a ceramic raw material; and these components are mixed and grounded to form a slurry. A pre-treated polymer sponge is impregnated in the slurry for slurry coating treatment and a barium titanate foam ceramic is obtained after drying and sintering. Then, through dopamine modification, micrometer/nanometer silver is deposited in situ on a skeleton surface. A resin, which is in the molten state and is thermosettable, is immersed into pores of the modified barium titanate foam ceramic, and the modified barium titanate foam ceramic/thermosetting resin composite material is obtained after a thermosetting treatment.
