Exploring the impact of YBa2Cu3O7-x superconductor on optical properties of PS-PMMA composites: Insights into band gap and dielectric behavior.

Yttrium barium copper oxide)YBa2Cu3O7-x(is one of the most interesting high-temperature superconductors. YBa2Cu3O7-x was synthesized by mixing yttrium oxide, barium dioxide, and copper oxide and applying the combustion process heated (Burn process) at 1123 ok. Then, the materials resulted in a grinding, pressing, and calcification process at 1023 ok for three hours under the flow of oxygen. This study focused on the impact of YBa2Cu3O7-x on blended polymer poly (methyl methacrylate)-polystyrene (PS-PMMA) to fabricated (PS-PMMA-YBa2Cu3O7-x) composites applying a dissolving-solution-cast method. The optical properties of composites were investigated using different loading ratios from (0, 3, 6, 9, and 12 wt. %) of the superconductor materials. The optical properties result of composites exhibited notable improvement in the absorbance, absorption index, refractive coefficient, and real and imaginary isolation constants with an increase in the YBa2Cu3O7-x concentrations. In contrast, significant enhancement was presented by reducing the energy gap up to 1.5 eV after the contribution of the (YBa2Cu3O7-x) superconductor. Fine homogeneity of the blended polymers in the matrix presented optical microscopy (OM) images and good dispersion of the YBa2Cu3O7-x superconductor in the composites. These composites could open new ways for new applications for electronic devices such as solar cells and sensors, etc. [ABSTRACT FROM AUTHOR]
