Characterization of (PMMA-CoCl2)‎ composites

الملخص EN

In this paper, study the of effect cobalt chloride on optical properties of poly (methyl methacrylate).

The samples of composites were prepared using casting method with different concentrations of cobalt chloride (0,1,2,3) wt.

%.

The optical properties have been studied in the wavelength range (200-800) nm.

The results show that the optical properties (absorption coefficient, energy gap) and optical constants (refractive index, extinction coefficient and dielectric constants) change with increase of the cobalt chloride concentration.
