AB - The innovative objective of present work is to evaluate the optical properties of the pure PVC and PVC composites with 5 wt.% organosilicon. The composite of PVC /organosilicon has been prepared by casting method. The optical properties of pure PVC and PVC/organosilicon thin films were measured in the wavelength range (250–1300 nm) by utilizing the diffusive reflectance device at room temperature 307 K. The optical properties as: absorption, reflectance, transmittance, refractive index, dielectric constant, optical conductivity, urbach energy and skin depth were calculated. The energy gap of direct transition was decreased from (4–2.2 eV), and for the indirect allowed also decreased from (3.4–1.8 eV), these values indicated the PVC thin films effected by the organosilicon. In details, the urbach energy have been decreased accompanied declines the energy gap after PVC mixing with organosilicon. The dispersing energy and the effective single oscillator were increased. The high frequency of dielectric constant and effective mass were increased of thin films of PVC modified with organosilicon. XRD and SEM were employed upon the sample to demonstrate the semi-crystalline and porous structure. The modified thin films of PVC with organosilicon have many applications as optical stability in electronic applications, low fabrication cost, non-flammability, high heat borne, coating the inner lining of the rocket engine, and heat shielding material.
