gIn this Communication, the effect of varying mass fractions (0-20 wt.-%) of calcium chloride (CaCl2) salt on the alpha- and beta-phase content of poly(vinylidene fluoride) (PVDF) as-cast films were investigated. Spectral and X-ray studies revealed the maximum ferroelectric beta-phase for the addition of 15 wt.-% of CaCl2 in PVDF compared to neat PVDF samples. The dense beta-phase dominant PVDF-CaCl2 (15 wt.-%) thick film used as a ferroelectric insulator in one-capacitor (1C) type random access memory device exhibited a remnant polarization of 3.1 mu C .cm(2), and is a good indication that the unoriented PVDF-CaCl2 films can be used in electronic applications without further stretching process.
