Balkan et al. report the formation of coaxial nanotubes by the consecutive deposition of polyaniline and poly(hydroxyethyl methacrylate) on a template with mesoscopic pores [8]. The dissolution of the template results in the

• techniques allowed for fine-tuning of the thickness of the individual layers, keeping the functionalities of the polymers intact. The response of the single components and the coaxial nanotubes to changes in humidity was investigated for potential humidity sensor applications. For single-component conductive

Furthermore, fabricating conductive nanotubes using templates with mesoscopic pores resulted in the alignment of polymer chains parallel to the tube axis, increasing conductivity above that of nonaligned films [36].
