Ceramic sponge material with rebounding nanofiber framework and preparation method
The invention relates to the technical field of novel hierarchical pore materials and nanofiber materials. The invention provides a ceramic sponge material with a rebounding nanofiber framework and apreparation method. The preparation method comprises the following steps: taking silica sol, water-soluble carbon black and monatomic silicon particles as initial raw materials to prepare a uniformlyand stably dispersed suspension; taking pretreated organic foam as a template, impregnating the suspension, extruding or throwing slurry, drying to obtain an organic foam prefabricated body, and carrying out reactive sintering in different atmospheres to finally obtain the hierarchical pore structure ceramic new material woven by nanofibers with resilience. The method has the characteristics of low cost, no need of expensive equipment, simple process, high-efficiency synthesis and easiness in industrial production, and the obtained nanofiber woven ceramic sponge has the characteristics of excellent comprehensive performance, such as high porosity, good permeability, high specific surface area, resilience, heat insulation, organic matter adsorption and the like.
本发明涉及新型多级孔材料、纳米纤维材料技术领域，提供了一种具有可回弹纳米纤维构架的陶瓷海绵材料及制备方法,所述制备方法以硅溶胶、水溶性炭黑及单质硅颗粒作为初始原料配制均匀稳定分散的悬浮体，利用经过预处理的有机泡沫作为模板，浸渍上述悬浮体并挤压或甩浆、干燥得到有机泡沫预制体，通过在不同气氛下进行反应烧结，最终得到具有可回弹特性的纳米纤维编织而成的多级孔结构陶瓷新材料。本发明具有低成本、无需高昂设备、工艺简单、高效合成、易于工业化生产的特点，所得纳米纤维编织陶瓷海绵综合性能优越：高气孔率、良好渗透性、高比表面积、可回弹、隔热、有机物吸附等特性。
