Two parts of research have been done in this thesis the study of gas sensor based on nano-zeolite and carbon black polymer filmsIn the first part, the gas sensor based on nano-zeolite film has been studied to detect the nerve simulate gases. This sensor presents high sensitivity, quick response and the miniaturigation. This research work will provide a novel way to quickly detect the nerve agent gas in order to fight against terrorism and chemistry war.The study of the sensor based on the conventional zeoli...
