Replication Data for: Impact of Bulk Conduction Phenomena on the Temporal Stability of Piezoelectric Behaviour of Engineered PDMS Ferroelectrets

The data covers: Piezoelectric d33 Coefficient Stability: Time-dependent measurements for ferroelectrets of different thicknesses (600–1400 μm) poled at 5 and 6 MV/m. Surface Potential and Conductivity: Measurements of conductivity versus surface potential for PDMS films charged via impulse and corona methods, along with the apparent distribution of charge traps below the conduction band.

Surface Potential Decay: Analysis of decay rates versus surface potential for impulse and corona-charged PDMS films, including log-log representations at different initial potentials. Polarization-Electric Field Characteristics: First and fifth voltage loop measurements for polypropylene and PDMS ferroelectrets of varying thicknesses (600–1400 μm), including comparisons between ferroelectrets and unstructured PDMS films.
