YCYuhao Chen GLGuang Liu YCY J Cui

Key Points

To investigate the effects of PVA doping on the dielectric properties and energy storage performance of PMMA composites.
Incorporation of PVA into PMMA at ultra-low concentrations.
Measurement of dielectric constant and dielectric loss of the composites.
Assessment of energy storage density of the modified PMMA.
Significant increase in dielectric constant with minimal increase in dielectric loss.
Enhanced energy storage density achieved in the PVA-doped PMMA composite.

Abstract

By incorporating a small amount of PVA into PMMA, the dielectric constant of the composite dielectric was significantly increased with only a slight rise in dielectric loss, ultimately yielding a desirable energy storage density.
