| 摘 要： | 分别采用水热和静电纺丝法制备出一维ZnO、TiO_2、SnO_2纳米材料,并对其气、湿敏特性进行了研究.结果表明一维纳米材料具有非常快的响应恢复速度:水热法制备的花状ZnO纳米棒束由11%RH到95%RH的响应时间约为5 s,恢复时间约为10 s;静电纺丝法制备的掺杂KCl的TiO_2纳米纤维由11%RH到95%RH的响应时间为3 s,恢复时间约为4 s;静电纺丝法制备的SnO_2纳米纤维对50 ppm(1 ppm=10-6)甲苯气体的响应时间仅为1 s,恢复时间约为5 s.

| Abstract: | One-dimension ZnO, TiO_2 and SnO_2 have been prepared via hydrothermal and electrospinning methods, and their sensing properties to gas and humidity have been investigated. These one-dimension nanomaterials exhibit quick response and recovery. The response and recovery times of ZnO nanorods (from 11%RH to 95%RH) prepared by hydrothermal method are 5 and 10 s respectively, the response and recovery times of KCl-doped TiO2 nanofibers (from 11%RH to 95%RH) prepared by electrospinning method are 3 and 4 s respectively, and the response and recovery times of the SnO_2 nanofibers prepared by electrospinning method to 50 ppm toluene are about 1 and 5 s respectively. |
