The invention discloses isotropic three-dimensional communicated porous wave-absorbing ceramic and a preparation method thereof, and relates to the technical field of porous ceramic wave-absorbing materials.The method comprises the following steps that ceramic powder and lignocellulose are dispersed in deionized water and stirred to be uniform, and a mixed solution is obtained; pouring into a mold, freezing, performing vacuum freeze drying, and removing the mold to obtain a green body; and carrying out thermal cracking to prepare the isotropic three-dimensional communicated porous wave-absorbing ceramic. The porous wave-absorbing ceramic provided by the invention has good high temperature resistance, machinability and excellent wave-absorbing performance, and has potential application prospects in the field of wave absorption. The invention solves the problems of tedious preparation process and high cost of the existing wave-absorbing ceramic material.

This invention relates to the field of cosmetic technology, specifically to a salicylic acid supramolecular complex, its preparation method, and its applications. The components include salicylic acid, panthenol, and cyclodextrin; the weight ratio of salicylic acid to panthenol is (20-79):(40-59). The salicylic acid supramolecular complex prepared by this invention improves upon the inherent defect of salicylic acid's poor water solubility due to its lipid solubility. Furthermore, the prepared salicylic acid supramolecular complex maintains good solubility in various complex formulation systems containing commonly used cosmetic solvents such as ethanol and polyols.
