Novel glass materials-based (PVA/PVP/Al2O3/SiO2) hybrid composite hydrogel membranes for industrial applications: synthesis, characterization, and physical properties

Abstract Metal oxides e.g., Al 2 O 3 and SiO loaded-hydrogel blended membranes composed of poly(vinyl alcohol)/poly(vinyl pyrrolidone) (PVA/PVP, PVA/PVP/Al , PVA/PVP/SiO /SiO ) were successfully prepared on precleared glass plates by dip coating method. Meanwhile, series obtained crosslinked hydride composite hydrogel using solution-casting Samples have been characterized for use in microelectronic devices. Results X-ray diffraction revealed that the structure doped sample with nanoparticle has a polycrystalline (hexagonal Orthorhombic), while FE-SEM micrographs show grains nanoscale homogenous nature membranes. Interestingly, optical measurements composites recorded UV/Vis spectrometer. The parameters such as refractive index energy gap estimated. Moreover, complex dielectric constants calculated optically all composites, experimental data shows additive nanoparticles direct band gap. Where, E g at 1.82, 2.55, 1.95 eV), respectively. While PVA/PVP an indirect value 2.24 eV. Finally, frequency dependence transport properties was measured, where results showed improvement behavior metal loading. can be used optoelectronics
