Abstract

Aligned carbon nanotubes (CNTs) make a promising platform for thermal radiation applications due to their broadband IR hyberbolic dispersion and their ability to withstand high temperatures. However, their temperature dependent optical properties remain to be explored. Previously, the thermal stability of CNTs have been studied in helium and hydrogen atmospheres and vacuum, yet ambient air is yet to be explored. Here, we study optical properties of aligned CNTs at high temperatures in ambient air. We show that these films can withstand high temperatures when coated with a thin layer of dielectric and exhibit broadband IR hyperbolic dispersion at elevated temperatures.
