Welcome to AFOSR-MURI

Carbon nanomaterials, including 1D carbon nanotubes (CNTs) and 2D single-atomic layer graphene, have been demonstrated to show superior thermal, electrical, and mechanical properties. Due to their dimensionally confined structures, however, these 1D and 2D nanomaterials exhibit strong direction-dependent thermal and electrical transport properties with extremely low out-of-plane conductivities. The objective of this MURI program is to extend the unique properties of these nanostructures to the critical third dimension by assembling nanotubes and graphene sheets to fabricate tunable 3D nanoporous hybrid architectures possessing unique thermal, electrical and mechanical properties in the three-dimensions. The nanofabrication efforts will be complemented by detailed chemical and multiscale microstructural analysis as well as physical property evaluation. Multiscale-multiphysics modeling and simulation tools will be developed to provide guidance to the design of the 3D material architectures, protocols for their synthesis and assembly, structure-property optimization, and process scalability. With 3D nanoscale porosity, large surface area, and exceptional mechanical and transport properties, these nanostructures are promising for numerous applications. The highly multidisciplinary nature of this project also provides unique opportunities for training interdisciplinary students and postdoctoral scholars.
