Abstract

Individual poly(methyl methacrylate)/MWCNT doped with sulfuric acid were polymerized in situ to yield individual nanotubes with increased electrical conductivity. In the presence of aliphatic alcohol vapors of various diameters, the Nanocomposites were measured as a function of time. These sensor responses are particularly rapid due to the huge surface to volume ratio, consistent diameter, and limited amount of active material employed in the design. Individual nanotube sensors demonstrate actual saturation when exposed to and removed from the detecting gas. In addition, a chemical sensing system was created employing a nanocomposite film in both air and vapor alcohol gas. When exposed to alcohol, the surface reaction was immediate, with virtually total current recovery after pumping out the alcohol, making it a reusable sensor with rectifying behaviour.
