Title: Nanostructured Super-Black Optical Materials
Agency: NASA
Contract: NNX12CE59P
Award Amount: $124,634.00


NASA faces difficulties in imaging and characterizing faint astrophysical objects within the glare of brighter stellar sources. Achieving a very low background requires control of both scattered and diffracted light. Aligned arrays of carbon nanotubes have recently been recognized as having world-leading optical absorption, far above competing state of the art materials. The GSFC team noted that nanotube arrays have the "potential to provide order-of-magnitude improvement over current surface treatments and a resulting factor of 10,000 reduction in stray light when applied to an entire optical train." While excellent performers, NanoLab recognizes that the nuances of the array structure, such as angular alignment, diameter, length, and top-surface roughness of the array play a major role in their optical properties, and these need to be characterized if we wish to control and tailor these materials for specific applications. Further, the arrays grown to date are often poorly adhered to their substrates, which are typically silicon. NanoLab plans to develop processes grow arrays on flexible, tougher substrates such as Ti and stainless steel foils, so they can be formed and inserted into optical systems without damage. We will correlate the VIS-IR optical properties to the array structure and to the process parameters that generate them.Ball Aerospace will assist NanoLab in this effort with BRDF and other optical measurements.
