Abstract

The thermal characterization of single-walled carbon nanotubes (SWCNTs) and tungsten oxide (WO3)-based nanomaterials through the use of Raman spectroscopy is the primary aim of this study, and is focused mainly on the applications of SWCNTs for energy storage and WO3for toxic gas sensing, respectively. In the case of SWCNTs, the properties relevant to their performance obtained via resonant Raman spectroscopy were thermal expansion and thermal conductivity through the exploitation of the latter property’s relationship to the thermal behavior of the Raman G+-band of SWCNTs. In the case of the tungsten oxide-based nanomaterials, the responses of the various Raman signature peaks to different external stimuli, such as temperature variation, humidity changes, and toxic gas exposure, under controlled conditions were investigated.
