Preparation method of biomass carbon aerogel composite material, biomass carbon aerogel composite material and application of biomass carbon aerogel composite material
The embodiment of the invention relates to the technical field of functional materials, in particular to a preparation method of a biomass carbon aerogel composite material, the biomass carbon aerogel composite material and application of the biomass carbon aerogel composite material. According to the method, biomass aerogel loaded with ZIF-8 particles is immersed in a second mixed solution, a ZIF-67 layer can grow on the outer surface of each ZIF-8 particle, and target aerogel is obtained. The target aerogel comprises biomass aerogel and a double-layer metal organic framework, wherein the double-layer metal organic framework is distributed in pores of the biomass aerogel and is formed by coating the outer surfaces of ZIF-8 particles with a ZIF-67 layer. The biomass carbon aerogel composite material loaded with Co and ZnO can be obtained by carrying out carbonization treatment on the target aerogel. Wherein Co has magnetism and is used for carrying out magnetic loss on electromagnetic waves, and ZnO is used for carrying out dielectric loss on the electromagnetic waves. The porous structure of the aerogel and the porous structure formed after carbonization of the double-layer metal-organic framework can effectively improve the impedance mismatch phenomenon, and the wave absorbing performance of the biomass carbon aerogel composite material is improved.
本申请实施例涉及功能材料技术领域，特别是涉及一种生物质碳气凝胶复合材料的制备方法、生物质碳气凝胶复合材料及其应用。在该方法中，将负载有ZIF‑8颗粒的生物质气凝胶浸入第二混合溶液中，可以在ZIF‑8颗粒的外表面生长ZIF‑67层，得到目标气凝胶。目标气凝胶包括生物质气凝胶，以及分布在生物质气凝胶的孔隙中由ZIF‑67层包覆在ZIF‑8颗粒的外表面而形成的双层金属有机骨架。通过对目标气凝胶进行碳化处理可以得到负载有Co和ZnO的生物质碳气凝胶复合材料。其中，Co具有磁性，用于对电磁波进行磁损耗，ZnO用于对电磁波进行介电损耗。气凝胶的多孔结构和双层金属‑有机骨架碳化后形成的多孔结构可以有效改善阻抗失配现象，提高生物质碳气凝胶复合材料的吸波性能。
