MODIFIED BARIUM TITANATE FOAM CERAMIC/THERMOSETTING RESIN COMPOSITES AND PREPARATION METHOD THEREOF
Disclosed are a modified barium titanate foam ceramic/thermosetting resin composite material and a preparation method therefor. 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 same are mixed and ground so as 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 in-situ deposited 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 a modified barium titanate foam ceramic/thermosetting resin composite material is obtained after a thermosetting treatment.
