Abstract
An electrically-conductive polypyrrole film is formed, on a non-conducting substrate, by contacting the substrate with pyrrole and an oxidising agent in a solvent, or with the colloidal polypyrrole that is the reaction product thereof, and removing the substrate while the film is at least substantially transparent, e.g. 50 to 250 nm thick. A gas sensor comprises a chemiresistor prepared by this process.
