Novel method of fabrication of doped polyaniline nanostructures

Micro and nanostructures of doped polyaniline are grown directly on a ground glass surface. An in situ vapor phase chemical oxidative polymerization, directed by the oxidant which has been pre - deposited on the ground glass surface, is used to obtain the micro/nano structures. The morphology of these structures is studied using optical microscopy and field emission scanning electron microscopy. Formation of different types of one-dimensional nanostructures like tubules, fibers, wires and even ribbon-like structures is indicated. The structures obtained have a wide range of size distribution and also different geometries. Infrared spectroscopic characterization of the obtained polyaniline nano/microstructures also indicates the presence of well-ordered doped polyaniline chains. The present work reports a novel, convenient and economical technique for obtaining polyaniline nanostructures and has high technological importance.
