Herein, we report on the fabrication of carboxylated polypyrrole nanotubes (CPPy NTs) using template synthesis combined with vapor deposition polymerization. Chemical polymerization of carboxylated pyrrole vapors within cylindrical pores of template is capable of providing several advantages such as homogeneous functionalities and tailored morphology. Two different monomers (pyrrole-2-carboxylic acid, pyrrole-3-carboxylic acid) were employed, and ferric chloride was used as an oxidizing agent. The resulting CPPy NTs showed smooth surface, hollow inner structure, and opened pores. In addition, their wall-thickness and length were ca. 18 nm and ca. 15 μm, respectively. The carboxylates on the nanotube surface were confirmed by Raman, FT-IR, X-ray photoelectron spectroscopy. Finally, these functionalized polymer nanotubes were successfully used as DNA carriers, molecular probes, electronic noses, and glucose/DNA sensors. |
