Selampinar, F.Toppare, L.Akbulut, U.Yalçin, T.Süzer, Ş.2016-02-082016-02-0819950379-6779http://hdl.handle.net/11693/25887Pure polypyrrole (PPy) and polypyrrole-polyamide (PPy-PA) composite films were synthesized electrochemically. The gas-sensing ability was investigated for both pure PPy and PPy-PA films. The composite films' response to several gases are better defined and reproducible compared to pristine conducting polymer. Electrochemical behaviour of PPy and PPy-PA electrodes in the presence of pyrrole and pyrrole-free medium is investigated via cyclic voltammetry. Mass spectrometry studies strictly reveal that the composite is completely different to a mechanical mixture. This phenomenon is discussed in comparison to polyaniline-polycarbonate composite. © 1995.EnglishCompositeGas sensorChemical sensorsCopolymerizationCyclic voltammetryElectric conductivity measurementElectrochemistryElectrodesGrafting (chemical)Mass spectrometryPolyamidesPolycarbonatesSynthesis (chemical)PolypyrroleOrganic conductorsArticle10.1016/0379-6779(94)02299-E
