Effect of particles size on the optical constants of iron/polystyrene composites via UV-radiation

摘要: The present study deals with the optical characteristics of polystyrene (PS) composites containing iron particles different sizes: 5, 40, 110, and 250 μm. absorption spectra were collected in wavelength range 300–800 nm using a UV-spectrophotometer. results obtained analyzed terms formula for non-crystalline materials. energy gap other basic constants such as refractive index, dielectric constants, conductivity investigated showed clear dependence on size. It was found that iron-filled is less than neat PS, it decreases particle size decreases. index prepared determined from transmittance reflectance spectra. calculated constant increase when d...
