Recent Advances in Carbon Nanotube Forests:
The promise of carbon nanotubes (CNTs) as a “wonder material” has thus far failed to live up to the initial hype. Individual CNTs demonstrate high modulus (1TPa) and strength (50 GPa) while maintaining flexibility. Thermal and electrical transport properties likewise exceed conventional engineering materials. When dense populations of CNTs are synthesized into vertically-oriented films for large scale applications, however, the beneficial properties fail to scale in a in a volumetric manner. These CNT populations, known as CNT forests or CNT arrays, feature a complex and intertwined morphology which tend to dictate their ensemble properties. In this talk, I will discuss mechanisms responsible for inhomogeneous CNT forest morphology and highlight simulation, synthesis, and processing advances from within my research group towards the goal of optimizing CNT forest properties for specific applications.
