Effect of Accelerated Thermal Ageing on the Selective Solar Thermal Harvesting Properties of Multiwall Carbon Nanotube/Nickel Oxide Nanocomposite Coatings
Figure 6
Fingerprint Raman spectra for a typical before and after thermal ageing test. The main phonon peaks due to NiO (~524 and ~1100 cm−1) and carbon ( cm−1 and cm−1) clearly show a loss of carbon after ageing test.
