Abstract

The ferroelectric β-phase in a poly(vinylidenefluoride-trifluoroethylene-chlorotrifluoroethylene) film is successfully formed using a room temperature solvent-annealing process and shows enhanced ferroelectricity compared to a thermally annealed film. Applications in electronics and energy are demonstrated with significantly enhanced device performances for a solvent annealing (SA) film employed devices compared to a thermal annealing film employed due to enhanced ferroelectricity of the SA film.
