Thermal imaging and analysis of carbon nanotube composites
Carbon nanotube (CNT) films have a broad range of applications, from solar cells and transistors to bolometers and mechanical reinforcement additives for polymers. However, surprisingly little is still known about the thermal properties of such CNT films, and in particular about the intertube …
