| description | Polyvinyl alcohol (PVA) and Neodymium (III) oxide (Nd<sub>2</sub>O<sub>3</sub>) were combined to synthesized flexible innovative PVA/Nd<sub>2</sub>O<sub>3</sub> polymer composite samples utilizing a solution casting approach for use in dielectric devices. The XRD, FTIR, and SEM methods are all investigated to characterize the composite films. In a frequency of 50 Hz to 5 MHz, the effects of additive Nd<sub>2</sub>O<sub>3</sub> on the dielectric behavior of PVA were recorded. The PVA/Nd<sub>2</sub>O<sub>3</sub> composite films were successfully fabricated, as shown by XRD and infrared spectroscopy. The scanning microscopy pictures showed that the Nd<sub>2</sub>O<sub>3</sub> was loaded and distributed uniformly throughout the PVA. After the incorporation of Nd<sub>2</sub>O<sub>3</sub>, the composite PVA/Nd<sub>2</sub>O<sub>3</sub> has a conductivity of 6.82 <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mo>×</mo></semantics></math></inline-formula> 10<sup>−9</sup> S·cm<sup>−1</sup>, while the PVA has a conductivity of 0.82 <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mo>×</mo></semantics></math></inline-formula> 10<sup>−9</sup> S·cm<sup>−1</sup>.
