Single-walled Carbon nanotubes/Conducting polymerbased sensor array for detection of toxic gases |
| 초록 |
We have fabricated gas sensors using single-walled carbon nanotubes(SWNTs)/polyaniline(PAni) composite by drop coating method on a silicon substrate. The sensor conductance decreases under NH3 atmosphere, whereas it increases under CO atmosphere at room temperature. Compared with the sensors made of SWNTs without PAni, SWNTs/PANI sensors exhibit faster response and better sensitivity over a variety range of concentrations. We have also investigated structure and morphology of SWNTs/PAni composites to study the relation between their structural properties and electrical properties. |
