静电纺丝ZnO/SnO2复合纤维及其丙酮敏感性能
Electrospun ZnO/SnO2 Composite Fibers and Their Acetone Sensitivity
摘要: 采用静电纺丝技术结合退火煅烧的方法制备了高性能的ZnO/SnO2基复合纤维材料丙酮气体传感器，通过各种表征技术对样品的形貌结构进行了分析。气敏测试发现，这种复合纤维材料在325℃对100 × 10−6的丙酮气体的响应为23.66，响应/恢复时间为2 s和69 s，即使丙酮浓度低至10 × 10−6响应依然可以达到3.39。制作的ZnO/SnO2基气体传感器对甲醇、氨气、甲苯、丙酮、三氯甲烷、DMF和冰乙酸表现出良好的选择性，此外还有很好的重复性和稳定性。这些归功于其独特的一维网状特殊形貌和其内部存在大量的n-n型异质结。
Abstract: A high performance acetone gas sensor based on ZnO/SnO2 composite fiber material was prepared by electrostatic spinning and annealing calcination. The morphology and structure of the sample were analyzed by various characterization techniques. The gas sensitivity test shows that the composite fiber material responds 23.66 to 100 × 10−6 acetone gas at 325˚C and the response/recovery time is 2 s and 69 s. Even the acetone concentration is as low as 10 × 10−6, the response can still reach 3.39. The ZnO/SnO2-based gas sensor shows good selectivity to methanol, ammonia, toluene, acetone, trichloromethane, DMF and glacial acetic acid, as well as good repeatability and stability. These are attributed to the unique one-dimensional network morphology and the existence of a large number of n-n type heterojunctions.
