摘要：

In this paper, the humidity sensing properties of multi-walled carbon nanotubes modified with LiClO4 are investigated. The new sensing material is characterized by FESEM, FTIR, Raman, ICP and XPS. For comparison, the humidity sensing characteristics of the four conventional materials MnWO4 (hubnerite), BaTiO3 (perovskite), NiWO4 (huberite), and ZnCr2O4 (spinel) are also discussed. The selectivity of the new humidity sensing material is studied. Finally, the response to water vapour of the new sensing material is discussed by using a dynamic testing method.
