Comparison study on the dielectric constant value at 1 kHz for PVDF/MgO and PVDF-TrFE/MgO.

Author	Findings	Ref.
Mahdi et al.	Film prepared by solution casting with thickness of 25 μm. Dielectric constant was obtained for unfilled PVDF-TrFE 7.2 at 1 kHz, with tangent loss of 0.1 at similar frequency.	[37]
Singh et al.	PVDF-TrFE/MgO prepared by solution casting with 20 μm thick film. However, no dielectric constant value was recorded.	[38]
Chen et al.	Addition of MgO into PVDF with varying loading percentage between 1 and 4%. The dielectric constant value decreased with increase in MgO loading. Dielectric constant recorded at a frequency of 1 kHz was 7.5.	[39]
