POSS functionalized alumina ceramic fiber and sol-gel spinning preparation method thereof
The invention discloses a POSS functionalized alumina ceramic fiber and a sol-gel spinning preparation method thereof. The preparation method of the aluminum oxide ceramic fiber comprises the following steps: mixing a POSS monomer with a functional group with an aluminum source in an organic solution, adding a certain amount of a catalyst, stirring and reacting for a certain period of time, preparing the fiber through sol-gel spinning, and finally calcining to prepare the POSS functionalized aluminum oxide ceramic fiber. The aluminum oxide ceramic fiber is composed of aluminum oxide and a small amount of POSS, the diameter is 5-100 micrometers, the length is larger than 500 m, the breaking strength is 1-3 GPa, the modulus is 300-500 GPa, and the use temperature is 1200-1600 DEG C. The method overcomes the defect of poor manufacturability of the traditional method, and is beneficial to obtaining the high-temperature-resistant continuous ceramic long fiber.
本发明公开了一种POSS功能化的氧化铝陶瓷纤维及其溶胶‑凝胶纺丝制备方法。该氧化铝陶瓷纤维的制备方法包括：将带有功能基团的POSS单体与铝源在有机溶液中混合，加入一定量的催化剂，搅拌反应一定时间后，通过溶胶‑凝胶纺丝制备纤维，最后煅烧制备得到POSS功能化的氧化铝陶瓷纤维。该氧化铝陶瓷纤维由氧化铝和少量POSS组成，直径5～100微米，长度大于500米，断裂强度1～3GPa，模量300～500GPa，使用温度1200～1600℃。该方法克服了传统方法工艺性差的缺点，有利于获得耐高温连续陶瓷长纤维。
