Optical Characteristics of Antireflective Materials Based on Polymers with Carbon Nanomaterials

Methods of laser treatment and oxygen plasma treatment for the anti-reflective coatings on the basis of composite materials filled by epoxy polymer with multi-walled carbon nanotubes are demonstrated. The influence of structuring the surface of composite materials by different methods on the reflectivity in the UV, visible, near and middle IR wavelength ranges has been investigated. The possibility of creating composite structures with low reflectance in the range of 0.2 - 25 µm, corresponding to the requirements for anti-reflection coatings of optical and optoelectronic systems of spacecraft and ground-based systems, has been demonstrated.
