Abstract:
Strong interactions are present in as-grown carbon nanotube. When carbon nanotubes are used in macroscopic forms of composites, the properties of the ensemble are often governed by the characteristic interaction and the morphology of the percolating nanotube networks, while the intrinsic attributes associated with a single, individual nanotube become less apparent. Experiments and theoretical models were developed to study this interaction, and ultimately to optimize the fabrication of carbon nanotube composites and networks. Short carbon nanotubes can be produced via sonication cutting. The same process can be applied to determine the strength of nano-filaments of different natures. Rheometry was found to be useful to provide qualitative information about the spatial distribution and orientation of carbon nanotubes in a liquid medium. In all, the choice of dispersion and processing techniques determines the final microstructure, there it plays a critical role in varying the physical properties and subsequent applications of the carbon nanotube/ polymer composites. The studies presented here have also paved new ways to tailor the electrical properties of generic carbon nanotube-polymer composites, and to create structures for soft electrodes and conductive networks for transparent flexible coatings.
