Abstract

A unique nanocomposite of poly (3-methylthiophene) with functionalized multiwalled carbon nanotubes (MWNT) has been synthesized that shows selective sensing for halogenated methanes. The sensor has been found to give the highest response for chloroform and none for methane. A tentative model has been proposed for this selective sensing of halogenated methanes.
