Pristine (carboxylated) and aminated polypyrrole nanotubes were successfully fabricated using vapor deposition polymerization with a template. In particular, aminated polypyrrole nanotubes were readily synthesized by modifying the nanotube surface with open polyamine chains. Pristine and aminated polymer nanotubes were used as the transducer to acetic acid vapor. Amino-functionalized nanotubes revealed more enhanced sensitivity than the pristine carboxylated nanotubes with the increasing number of amine spacers due to the increased polymer/analyte partition coefficient and mass uptake of the analyte. Moreover, polyamine-functionalized nanotubes presented a reversible and reproducible response to acetic acid up to 40% sensitivity. The aminated polypyrrole nanotubes demonstrated the potential capability to be excellent transducers for volatile fatty acids in disposable sensors.
