Tunable optical and dielectric properties of polymeric composite materials based on magneso-silicate

[摘要] Magneso-silicate (MgSi) as an inorganic ion exchange material was synthesized by a precipitation technique. Then, the MgSiwas impregnated into polyacrylamide acrylic acid and its composites (Poly) by condensation polymerization. To study the effect of $\gamma$-radiation, the polyacrylamide acrylic acid and its MgSi samples were synthesized using $\gamma$-irradiatingsystems at 25, 65 and 90 kGy. The variations in the radiation dose and amorphous structure were altered and confirmed by X-ray diffraction (XRD). Moreover, the absorbance and band-gap energy were enhanced by inserting MgSi into the polymeric composites (Poly). Furthermore, variations in temperature with dielectric constant, dielectric loss and conductivity of thesamples at various frequencies from 100, 500, 1000, 2000 to 4000 Hz have been explained.
