Title:
HIGH-ENTROPY ALLOY SULFIDE/TWO-DIMENSIONAL NANO COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/197954
Kind Code:
A1
Abstract:
The present application relates to the technical fields of electromagnetic wave absorbing material technologies, new energy electrode materials, and electro-catalysis, and discloses a high-entropy alloy sulfide/two-dimensional nano composite material, a preparation method therefor, and an application thereof. According to the present application, zinc acetate, copper acetate, ferric acetate, nickel acetate, and cadmium acetate are dissolved in an organic solvent, then sulfide and a two-dimensional nano material are added, dispersed, and uniformly mixed for reaction, and the high-entropy alloy sulfide/two-dimensional nano composite material is prepared in situ in one step. According to the present application, tests show that a nano high-entropy alloy sulfide has an electromagnetic wave absorption effect in a wave band of 6-18 GHz, and after the nano high-entropy alloy sulfide is compounded with a two-dimensional nano material, the wave band of the electromagnetic wave absorption effect is expanded to 5-18 GHz, and the electromagnetic wave absorption capability is improved. Compared with a single metal sulfide, the high-entropy alloy sulfide/two-dimensional nano composite material prepared by the present application has better electromagnetic wave shielding capability, oxidation resistance, high temperature resistance, wear resistance, and stability.
