Abstract: Mono-dispersed Nickel oxide nanoparticles were directly formed on the carbon fibers through a facile in situ flame synthesis method. High magnification SEM and TEM study revealed that the nickel oxide nanoparticles have a polyhedral structure and are uniformly distributed on the surface of carbon fibers. The concentration effect of the precursor used on the growth of polyhedral nickel oxide nanoparticles on carbon fibers has been studied.

Abstract: A novel solid state and surfactant-free method has been developed for synthesis of polyaniline superstructure composed of dendritic nanofibers. The good crystallinity of the product is confirmed by XRD, while FT-IR analyses indicate the formation of highly doped emeraldine salt of polyaniline product. Microscopic observations show that the product is in the form of polyaniline dendrites with a less-than-40 nm fiber diameter. The unique growth mechanism of the superstructure in solid-state reaction has been discussed.
