Effects of NdO Nanoparticles on the Structural Characteristics and Dielectric Properties of PVA Polymeric Films.

Polyvinyl alcohol (PVA) and Neodymium (III) oxide (NdO) were combined to synthesized flexible innovative PVA/NdO 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 NdO on the dielectric behavior of PVA were recorded. The PVA/NdO composite films were successfully fabricated, as shown by XRD and infrared spectroscopy. The scanning microscopy pictures showed that the NdO was loaded and distributed uniformly throughout the PVA. After the incorporation of NdO, the composite PVA/NdO has a conductivity of 6.82 × 10 S·cm, while the PVA has a conductivity of 0.82 × 10 S·cm. Another improvement is the decrease in the relaxation time from 14.2 × 10 s for PVA to 6.35 × 10 s for PVA/NdO, and an increase in the dielectric constant of 0.237 for PVA to 0.484 at a frequency of 100 Hz. The results showed that the composite samples have considerable changes as flexible films in different applications, including batteries and electronic circuits.
