- Summary
- "A single-step, bottom-up technique based on a nanostructured conducting polymer has been used to fabricate sensors. Small amounts of aqueous solutions of aniline, a dopant, and an oxidant were placed on an interdigitated electrode array. Ultraviolet (UV)-irradiation of the solutions enhanced polymerization, yielding a highly porous film of polyaniline nanofibers with mean diameters of around 100 nm and lengths on the order of 1 [mu]m. Solutions that were not irradiated formed bulk-like polyaniline films. Nanofibers and bulk polyaniline sensors were exposed to vapors in an argon carrier gas including: chloroform, a weak proton donor; toluene, a vapor that causes polymer swelling; and triethylamine, which alters the doping level. Because of their higher surface areas, the response times of the fiber sensors were faster than those of conventional bulk polyaniline sensors. Sensors were also fabricated from polyaniline/metal nanocomposites using the same one-step technique. The response of the polyaniline/Ag nanocomposite sensor was about a factor of 2-3 times faster than the polyaniline nanofiber sensor exposed to gaseous triethylamine, probably due to the strong interaction between nitrogen atoms and the metal nanoparticles. The thermal stability of polyaniline and its composites was studied by thermogravimetric analysis. These results suggest methods for the advancement of simple and environmentally-friendly production of nanostructured polyaniline-based sensors and electronic devices"--Abstract, leaf iv
