Paper Abstract

Vertically aligned carbon nanotube arrays are world renowned for their excellent optical absorption properties. However, at low angles, they suffer from higher reflection coefficients, due to the aligned structure. NanoLab has researched the potential for carbon nanotube loaded paints, (now marketed as Singularity Black) to create a more randomized structure with high optical and infrared absorption that will have better grazing angle performance. Other drivers for the development of a paint version include the desire to apply these coatings in large areas, on lower temperature substrates, and at lower cost. This paper describes the structures necessary for highly absorbing black coatings, and reviews the approach and data collected for two products, Singularity Black paint and the vertically aligned nanotube coating adVANTA.
