摘　　要：以四氯化锡和三氯化锑为前驱体,通过静电纺丝技术制备了柔性透明的自支撑氧化锡锑(ATO)纳米纤维膜.研究结果表明,该柔性ATO纤维膜具有四方相金红石晶体结构,且呈无规的纤维网状分布.当前驱体煅烧温度分别为520℃和700℃时,纤维的平均直径为200和150 nm;组成纤维的颗粒的平均粒径为10和19 nm;可见光透过率为72%和80%;电阻率为5.23和2.20Ω·cm.该自支撑ATO纳米纤维膜还显示出优异的柔韧性,在弯曲500次后其电阻率基本不变.Flexible, transparent and self-standing Sb doped SnO2 （ ATO） nanofiber films were successfully fabricated by means of a low-cost and scalable electrospinning process, with tin tetrachloride and antimony tri- chloride as precursors. The as-prepared ATO nanofiber films are typical interconnected nanofiber networks and show a single SnO2 rutile crystal structures. With increasing the calcination temperature from 520 ℃ to 700℃, the average diameter of ATO nanofibers decrease from 200 nm to 150 nm, but accompanied by an increase in the average diameter of ATO nanoparticles. Meanwhile, the transmittance of the ATO nanofiber film increa- ses from 72% to 80%, while their resistance decreases from 5. 23 Ω·cm to 2. 20 Ω·cm. Importantly, after 500 cycles of bending, the self-standing ATO nanofibers show no obvious electrical degradation. The ATO nanofiber films show promise for application in many fields, such as flexible liquid crystal displays, solar cells and flexible and transparent functional electronics.
