摘要 采用溶胶一凝胶法结合静电纺丝技术制备了直径20~60nm的超细氧化铟(In2O3)纳米陶瓷纤维及纳米陶瓷纤维无纺布。采用XRD,IR,SEM,HR—TEM,TGA等分析方法对纳米纤维的形貌和显微结构进行了表征,并研究了其气敏特性。由700℃下煅烧的该超细In2O3纳米纤维所制备的气敏元件具有较好的反应和选择性,对甲醛气体表现出较快的响应和恢复速度。 In2O3 ceramic nanofibers with diameters around 20 -60 nm have been fabricated by sol-gel combined electrospin- ning process. The morphology and chemical structure of the as-prepared and calcined samples are analyzed by SEM, TGA, HRTEM, XRD and FTIR. The gas sensor fabricated by In2O3 ceramic nanofibers calcined at 700 ℃ has special gas sensing properties including high response and selectivity, fast response and recovery time to formaldehyde gas.
