Description
  • This contribution deals with synthesis and characterization of conductive nanotubes suitable for preparation of active layers of chemical gas sensors. Polypyrrole nanotubes were synthesized by chemical polymerization using soft-template method. Soft-templates were created by various azo dyes (methyl orange, methyl red, congo red, Acid RED 1). The aim was to clarify the mechanism of nanotubes formation using chemically and structurally similar molecules of azo dyes. The effect of different synthesis conditions (temperature, reaction time) on geometry of nanotubes was also investigated. Morphology of prepared structured and unstructured polypyrrole (PPY) was observed by scanning electron microscope (SEM). There were also determined geometric dimensions of prepared nanotubes by means of image analysis (width ~ hundreds of nanometers, length ~ units of micrometers).
