- •
A scalable one-step melt extrusion processing route for highly aligned PVDF-TrFE films.
- •
The optimized as-extruded PVDF-TrFE exhibited a coercive field of 24 kV/mm and a remnant polarization of 0.078 C/m2.
- •
After annealing, the remnant polarization increased to 0.099 C/m2 and reached to the theoretical limit (0.102 C/m2).
