Effect of Accelerated Thermal Ageing on the Selective Solar Thermal Harvesting Properties of Multiwall Carbon Nanotube/Nickel Oxide Nanocomposite Coatings

<table>A plot of the photothermal conversion efficiency against the MWCNT concentration. The efficiency of light-to-heat conversion is small when the concentration CNT is near zero but increases rapidly when just less than 10 mg of CNTs are added to same mass of NiO. Addition of CNT beyond 10 mg decreases the conversion efficiency.</table>
