Abstract: Disclosed are a micrometer/nanometer silver-loaded barium titanate foam ceramic 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 blank is obtained after drying; and then a barium titanate foam ceramic is obtained through sintering. Through dopamine modification, micrometer/nanometer silver is in-situ deposited on a skeleton surface so as to obtain a modified micrometer/nanometer silver-loaded barium titanate foam ceramic. The modified micrometer/nanometer silver-loaded barium titanate foam ceramic is then put into a newly prepared Tollens' reagent for further reduction so as to obtain a micrometer/nanometer silver-loaded barium titanate foam ceramic with a three-dimensional network skeleton structure.
