A nanocomposite of polypyrrole/carbon nanotubes prepared by in situ chemical polymerization shows improved conductivity the polypyrrole as compared with its pure form. Its application a sensor, made using simple spin‐casting technique, drastically increased sensitivity. The Figure field‐emission scanning electron microscopy (FE‐SEM) image SWNT/Ppy nanocomposite.
