Abstract
This paper reports on the results of experimental investigations of the optical absorption (in the wavelength range 200–1200 nm) by carbon-containing thin nanofilms formed on the surface of poly(vinylidene fluoride) upon its chemical functionalization. The optical spectra exhibit resonance absorption peaks in the photon energy range 2.5–3.0 eV. The IR absorption spectra contain lines attributed to the carbon-containing phase. The band structure, the density of states, and the optical constants of one-dimensional carbon chains with added hydrogen are calculated by the semiempirical tight-binding method. The results of the calculations are compared with the experimental optical spectra. It is demonstrated that the theoretical and experimental spectra are in satisfactory agreement.
