| Abstract | ||
| A study of the effect of thickness on the optical properties of Polystyrene – Kaolinite Composite of thickness (0.86,0.92,1.11) mm prepared by introduction of filler material (kaolinite) to matrix material (polystyrene) after toasting to powder with temperature degree(100 ͦ C)and drying and choose partical size (D<100 μm) and have been used also binder material poly vinyl chloride (PVC) and had been added to dissolved polymer matrix material in benzen with the state ratios and study of effect of thickness for samples after and befor irradiation γ- Ray irradiation from Co60of average energy (2.5 Mev) with radiation dose of (250 KGy) on optical properties for composite material and absorption increase but the transmission decrease as a data of waving length with increase the thickness, as well as it is found that the absorption coefficient of these samples increase with decrease thickness and also calculation of the optical constant carried out such as extinct coefficient , refractive index, reflectance ,real and imaginary part of dielectric constant after and befor irradiation. | ||
