摘　　要：综述了金属纳米纤维、半导体纳米纤维、陶瓷纳米纤维的研究进展,报道了一种制备SnO2纳米纤维的新方法-- 热爆形变合成法,采用该方法制备出了SnO2纳米纤维,经XRD、SEM和TEM分析表明,SnO2纤维的直径约20-100 nm, 其X-射线衍射谱与标准的SnO2衍射谱完全一致。用热爆合成法制备的SnO2纳米纤维,经过研磨还可以制成长度不同的纳米棒,这种材料尺寸均匀、无团聚、稳定性高、比表面积较大,有望提高对气体的灵敏度,发展成较为理想的气敏、湿敏、压敏基体材料。Recent advances in one dimensional inorganic nano - materials were summarized in terms of metals, semiconductors, and ceramics. A new method of producing SnO2 nano - fibers was reported, which was named the thermal explosive deforming synthesis (TEDS), SnO2 nano-fibers produced by TEDS were analyzed by XRD, SEM and TEM. As a result, the diameter of the fiber is about 20 - 100 nm, its diffractogram is the same as that of SnO2. Nano -rods of different length can be obtained by grinding these SnO2 nano - fibres, which have homogenous size, high rate of specific surface area, and are hard to be agglomerated. So they are promising to become an ideal material for gas sensor, humidity sensor, piezoresistive pick -up.
