Alternating atmosphere ceramization method of inorganic gel nanofiber
The invention relates to an alternating atmosphere ceramization method of inorganic gel nanofibers, which comprises the following steps: firstly, introducing the inorganic gel nanofibers into a desorption bath for pressurized desorption treatment, and then introducing the fibers into a replacement bath for solvent replacement treatment and reduced pressure drying, then introducing the fibers into a pre-burning area under differential drafting tension supplementary treatment to obtain thermal polycondensation fibers, and finally ceramizing the fibers in an alternating atmosphere calcining area to obtain the flexible ceramic nanofibers. Compared with the prior art, the grain size of the prepared flexible ceramic nanofiber is 5-30 nm, the average diameter of the fiber is 50-500 nm, and the softness is smaller than 300 mN.
本发明涉及一种无机凝胶纳米纤维的交变氛围陶瓷化方法，本发明首先将无机凝胶纳米纤维引入解析浴中进行加压解析处理，随后将纤维引入置换浴中进行溶剂置换处理和减压干燥，接着在差速牵伸张力补处理下将纤维引入预烧区中获得热缩聚纤维，最后在交变氛围煅烧区中使纤维发生陶瓷化，获得柔性的陶瓷纳米纤维。与现有技术相比，本发明制备得到的柔性陶瓷纳米纤维的晶粒尺寸为5～30nm，纤维平均直径为50～500nm，柔软度小于300mN。
