NFs acted as an oxidant to oxidatively polymerize aniline. Consequently, Mn O was completely consumed while PANl/TiO -NFs were formed. Composite fiber film having a PANI nanowire-on-TiO nano/microfiber hierarchical nano/microstructure was fabricated by electrospinning, calcinations and in situ polymerization [121], The photocatalytic electrodeposition of PANI in nanotubular TiO host matrice was recently reported by Janaky ef a/. [ 108]. TiO films were initially electrosynthesized on titanium foil by anodization at different voltages in fluoride-containing aqueous media, and then the PANI was electrografted onto the entire surface of... 

Recently, there have been some attempts to prepare PPV nanowires and nanotubes by electrospinning [380-382]. Electrospim nanofiber consisted of a binary blend of poly[2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) with regioregular P3HT or poly(9,9-dioctylfluorene) [380]. The resultant nanofiber was found to have the diameter of ca. 100-500 nm with tunable optical and charge transport properties. In this manner, electro-spiiming has been a powerful technique to fabricate polymer, ceramic and inorganic nanowire. Nanotubular structiu e and coaxial nanowire composite could be also fabricated with blend of soluble core and insoluble wall material by the electrospinning method. 

Metal and/or metal alloy nanowires/nanofibers have attracted considerable attention due to their potential applications in relation to transparent electrodes and metal catalysts with a ID structure. In this regard, metallic nanofibers such as Au, Cu, and Ni with high electrical conductivity have been prepared by electrospinning (Figure 13.3). Gries et al. suggested a new fabrication process for the synthesis of Au nanofibers. Au nanoparticles (NPs) were embedded within a matrix polymer of PVA (M = 195 000 g mol ) by electrospinning followed by the pyrolysis of PVA and a subsequent calcination step. The sintered Au NPs...
