文摘 传统的电阻型气体传感器大多基于金属氧化物半导体材料,其能耗高、响应灵敏度较差,无法满足工业气体检测的需求。随着近几年三维石墨烯材料研究的深入,三维石墨烯及其复合材料凭借其高的比表面积和电导率,成为近几年气体传感器的研究热点之一。本文从三维石墨烯的制备方法着手,对三维石墨烯基电阻型气体传感器的性能和应用进行了综述。同时针对目前三维石墨烯基气体传感器存在的响应恢复速度慢、生产规模小等问题,提出传感芯片微型化、生产智能化等解决方法,使其成为未来工业物联网的感应前端。
其他语种文摘 Most common chemiresistive gas sensors,based on metal oxide semiconductors,have high energy consumption and poor gas response,which are not suitable for gas detection in factory.With the development of the research on 3Dgraphene,3Dgraphene and its composites become a hotspot of gas sensor researches,because of its large specific surface area and high electrical conductivity.In this paper,the fabrication,performance and application of gas sensors based on 3Dgraphene and its composites were summarized.At the same time,in view of the slow response recovery speed and small production scale of the current 3Dgraphene-based gas sensor,solutions such as miniaturization and intelligent production of the sensor chip were proposed,so that it can become the front end of the industrial Internet of Things in the future.
