Scalable Templated Growth of Catalytic Nanostructure Arrays with Tunable Dimensions

This proposal outlines a scalable, low-cost method for the addressable fabrication of arrayed nanostructures that are fabricated directly on conductive, semiconductive or non-conductive supports. The method and techniques involved have already been demonstrated and extensively investigated by the PI where 10 200 nm diameter nanostructures can readily be produced. Furthermore, the incorporation of this method with Mainstream"s expertise concerning chemical vapor deposition growth of carbon nanotubes will readily produce ultra-high density and surface area nanotube arrays for high energy density ultracapacitor applications. Carbon nanotubes fabricated using this innovative technique will have a high degree of control and uniformity in their diameter, length and orientation. Also outlined in this proposal is a method recently developed by the PI to eliminate nanotube aggregation, further enhancing the ultracapacitor electrode surface area. Mainstream has partnered on this STTR with a leader in the field of carbon nanotube research, Prof. Kirk J. Ziegler. Prof. Ziegler will aid in certain fabrication steps and elucidate the properties of the fabricated carbon nanotubes.
