PEDOT nanorods have been fabricated using reverse cylindrical micelle-mediated interfacial polymerization without any templates and applied as chemical sensors for the detection of HCl and NH3 vapor. The PEDOT nanorods, shown in the Figure, display very stable conductivity. The chemical sensors can detect low vapor concentrations and exhibit a reversible and reproducible response.
