Abstract

The influence of carbon nanotubes (CNT) and graphene on the optical density of polysulfone (PSF) polymer films for radiation in the terahertz range was investigated. The influence of film thickness and nanoparticle concentration on the optical properties of composites was studied. It has been established that an increase in the concentration of nanoparticles and film thickness leads to an increase in the absorption capacity of the material. The studies of the absorption parameters of electromagnetic (EM) radiation in the terahertz (THz) range in films up to 100 µm thick showed the effect of the percolation structure of the embedded phase and the correlation of wavelengths and parameters of the composite material structures.
