Processing

Nanostructures such as nanotubes, nanowires and nanofibers possess wide range of useful properties. For example, carbon nanotube is predicted to exhibit high tensile strength (~30GPa) and elastic modulus (~ 1.0 TPa), high electrical (10-30 kS/cm) and thermal (~ 1500 W/mK) conductivities, ballistic transport, stability at moderate temperatures, low density and high aspect ratio. Semiconducting nanowires are also expected to exhibit ballistic transport and low thermal conductivity characteristics compared to their bulk counterparts. These superb properties have sparked greater technological interest in nanostructures. One of the major difficulties that have hindered the growth in practical applications of nanostructures is the assembly of trillions of nanostructures into robust binder-free cohesive macro-sized objects. Dr. Adu explores different processing and assembling techniques to transform the trillions of nanostructures into easily usable micro-sized materials that eliminate the use of binders without compromising the intrinsic and inherent superior properties of the nanostructures.
