2007-391 Polyanaline Nanofibers as Hydrogen Sensors

SUMMARY
Professor Kaner and colleagues have developed a method for sensing hydrogen using polyaniline nanofiber material. The approach utilizes detectable conductivity changes in the nanofiber material when exposed to hydrogen gas. This polyaniline sensor has advantages over traditional palladium-based sensors in that its phase change for detection is reversible and its synthesis is inexpensive.
