摘要: 本文报道了致密柔性的α-Al2O3纳米结构纤维的静电纺丝制备过程,表征了纤维的微观结构和断裂强度及断裂伸长率等力学性质,讨论了影响纤维性能的因素,结果表明,纤维厚度为30~50nm的纳米片构成,没有孔洞和裂纹,具有良好的抗热震性,同商品α-Al2O3纤维相比,具有较高的断裂强度及断裂伸长率.  

关键词: α-Al2O3, 柔性纤维, 纳米结构, 静电纺丝

Abstract: This paper reported the dense flexible α-Al2O3 fibers with nanostructures fabricated by sol-gel-electrospinning process. The microstructure of fibers and mechanical properties such as fracture strength and elongation were characterized. Moreover, the factors affecting the fiber properties were discussied. The α-Al2O3 fibers were composed with 30~50nm nanoflakes, and no small holes or cracks were observed in those, which exhibted superior good thermal shock resistance and higher fracture strength and elongation compared with the commercial α-Al2O3 fibers.

Key words: α-Al2O3, Flexible fiber, Nanostructure, Eelectrospinning
