Paper Abstract

Chemical gas sensor that utilizes poly (2-vinypyridine)-carbon black composition as sensitive film is studied. Poly (2-vinypyridine)-carbon black was deposited on the interdigital microelectrodes via spin-coating method to detect organic vapor and humidity. To study the influence of the carbon black, poly (2-vinypyridine)-carbon black composites with different carbon black content were compared. The various characteristics such as sensitivity and selectivity of poly (2-vinypyridine)-carbon black based sensor have been studied. The results show that proper carbon black content and modified carbon black can improve the sensors' response characteristics.
