Embodiment
[0044] see figure 1 A method for preparing a variable-gap adsorption material based on porous ceramics, comprising the following steps:
[0045] S1. Prepare a porous ceramic material with large pores and open pores, clean it with deionized water, and dry it for later use;
[0046] S2. Immerse the porous ceramic material in a container filled with thermoplastic slurry M in a low-temperature molten state, and slowly extract air to form a vacuum, so that the slurry M is fully filled in the pores of the porous ceramic material, and the porous ceramic material is taken out. The airflow dredges the porous ceramics, removes the excess slurry M inside the ceramic pores, dredges the pores, and forms a phase change layer 1 on the surface of the ceramics and the inner wall of the pores after cooling to obtain a semi-finished product 1, such as figure 1 As shown, wherein A represents the porous ceramic material, and a represents the pore inner wall of the porous ceramic material;
