Abstract (summary)

Miscellaneous conducting polymer nanostructures have been investigated for their potential applications in sensors, energy storage devices and artificial motors. One-dimensional nanowires and nanotubes were synthesized chemically or electrochemically using a hard template replication technique. Their morphology can be controlled to some extent by tuning the synthetic conditions. Core-shell spheres with silica cores and conducting polymer shells have been fabricated. The electrical properties of individual nanoparticles were investigated and harnessed for chemical sensing. Their electrochemical properties were explored for energy storage applications.

These nanoparticles have been investigated as building blocks towards next-generation electronic devices. High-density arrays have been demonstrated through electric field-directed assembly or capillary force-assisted assembly of these nanostructures.

Composite nanowires with conducting polymer and magnetite nanocrystals have also been investigated. Materials embedded in the nanowires can bring additional functionalities into the conducting polymer system. This was exemplified by the development of an artificial motor with appropriate magnetic and catalytic properties which successfully achieved autonomous movement on designated pathways.
