The polymer poly(vinylidene fluoride) (PVDF) was irradiated with X-rays produced by a nonmonochromatic (MgKa) source and the structural and electronic PVDF surface modifications were studied by X-ray photoelectron spectroscopy (XPS). Changes in the shape and intensity of the C 1s and F 1s lines show

## Abstract In this Communication, the effect of varying mass fractions (0β20 wt.β%) of calcium chloride (CaCl~2~) salt on the __Ξ±__β and __Ξ²__βphase content of poly(vinylidene fluoride) (PVDF) asβcast films were investigated. Spectral and Xβray studies revealed the maximum ferroelectric __Ξ²__βphas
The surface of PVDF film was selectively modified by wet chemistry. Treatment with aqueous LiOH produced HF-elimination and the emergence of an oxygencontaining functionality. The XPS analysis clearly indicated the presence of ketone-, ether(epoxide)-, and alcohol motifs. The percentage of alcohols
