摘要: Multi-walled carbon nanotubes (MWCNTs) - polyvinylpyrrolidone (PVP) composite materials were applied as sensitive films of resistive gas sensors for the first time to detect 1,2-dichloroethane vapor. Four containing different quantities PVP prepared. The results revealed that got a larger sensing response compared with MWCNTs single-layer film. In addition, sensitivity vapor was improved due addition PVP. repeatability and long-term stability film studied well. Moreover, MWCNTs-PVP had good selectivity
