Ultra-low concentration PVA-doped PMMA: an all-organic dielectric with markedly improved dielectric properties and energy storage performance

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.
