Optical and structural properties of dye Juglone – Polymer blend prepared by solution mixing proses

The properties including the absorption coefficient, the coefficient of extinction, the refractive index for the dye Juglone – polymer blend (dJ-pb), and the results were studied. The “energy band gap” of the (dJ-pb) is 2.45 (eV) at room temperature. Moreover, the (dJ-pb) energy gap was measured using UV-visible spectra. FTIR spectra for the used by band values to investigate changes in the chemical composition of polymeric with distinct-additives. The (dJ-pb) was exposure to ultraviolet radiation. All the optical properties study before the UV Exposure.
