Controlling the optical properties and analyzing mechanical, dielectric characteristics of MgO doped (PVA–PVP) blend by altering the doping content for multifunctional microelectronic devices

The solution-cast method was used to synthesize magnesia (MgO) nanoparticles filled poly(vinyl alcohol) (PVA) and pyrrolidone) (PVP) blend matrix (80/20 wt %) based polymeric nanocomposite (PNC) films (i.e., [PVA–PVP]–x % MgO; x = 0, 0.06, 0.3, 0.6, 3.1, 6.25). Most of these PNC materials structures are amorphous, according an X-ray diffraction investigation. surface smooth homogeneous under SEM, confirming PVA PVP compatibility. MgO loading, on the other hand, enhanced roughness. According optical investigations, film's transmittance, energy bandgap decreased as Mg+2 -ions increased. Tensile strength has also improved from 5.92 MPa 10.65 MPa, while Young's modulus 51.16 166.4 MPa. From 100 Hz 1 MHz, dielectric electrical spectra were measured. Due nanoconfinement effect, it been determined that dispersion in PVA–PVP dramatically increases permittivity. With increasing frequency, permittivity decreases ac conductivity increases. When temperature a film is raised, nonlinear rise seen, dc follows Arrhenius law. I–V curves improve with increased ion concentration. These findings suggest PVA/PVP loaded NPs provides appropriate structural, optical, characteristics, expanding its potential industrial uses, particularly components devices.
