| Abstract | ||
| Polymer films of PEG and PVA and their blend with different concentrations of MnCl2(0,2,4,6 and 10 %.wt) were study using casting technique. The X-ray spectra of pure PEG,PVA and PVA:PEG films and with addition of 2% concentrations from (MnCl2) show amorphous structures. Theresults for FTIR showtheinteractionbetweenthefillerandpolymerblend resultsindecreasingcrystallinity with rich amorphous phase. This amorphous nature confirms the complexation between the filler and the polymer blend. The optical properties of (PVA:PEG/MnCl2) contain the recording of absorbance (A) and explain that the absorption coefficient (α), refractive index (n), extinction coefficient (ko) and the dielectric constants (real and imaginary part) increase with increasing the concentration of Composite(PVA:PEG/MnCl2). The optical energy gap for electrons transitions both are direct and indirect allowed. | ||
