Project Description

The objective of this project is to develop carbon nanotube (CNT)-ceramic (C) composite structures, in which vertically aligned (VA) carbon nanotubes are embedded in ceramic matrices for hot electrode applications such as magneto-hydrodynamic (MHD) power systems. Four objectives will be accomplished as follows: (1) Super growth of vertically aligned (VA) CNT carpets, (2) Fabrication of CNT-boron nitride (BN) composite structures, (3) Stability and resistance studies of the CNT-BN composite structures, and (4) Thermionic emissions from the CNT-BN composite structures.

Project Benefits

This project will provide appropriate composite structures for hot electrode applications without integrating all extreme properties within a single material. As well it may stimulate the extensive applications and commercialization of MHD power systems and establish a new family of VA-CNT base anisotropic composite structures. Overall, this could improve electricity generation efficiency in current combustion power plant and reduce the capital costs of MHD powered systems.
