Synthesis of interconnected polyaniline nanofibers in catanionic micelles

Interconnected polyaniline nanofibers with diameters in the range of 30-60 nm and lengths up to several micrometers have been synthesized by chemical oxidative polymerization of aniline in catanionic solution by mixing cetyltrimethylammonium bromide and sodium dodecylbenzenesulfonate. The product was characterized by field-emission scanning electron microscopy, transmission electron microscopy, UV-vis spectroscopy, and Fourier transform infrared spectroscopy. The effects of the molar fraction of cetyltrimethylammonium bromide on the morphologies of polyaniline have been investigated.
