Effect of 200 keV H+ ion implantation on films of poly(vinylidene fluoride)

Free-standing, flexible films of poly(vinylidene fluoride) were synthesized using sol-gel method. Effects of implantation of 200 keV H+ ions on these samples were studied. An apparent change in colour of the films, with ion implantation, was observed. Morphological studies revealed breaking up of larger spherulites into smaller ones with irradiation. Microstructural analysis revealed an increase in amorphous content with irradiation. Microscopic and vibrational spectroscopy (Raman and Fourier transform infrared spectroscopy) also point out to the loss of crystalline nature upon irradiation. Effect of ion implantation on the fraction of electroactive phases and the non-polar a phase has been discussed.

Automated summary

Free-standing poly(vinylidene fluoride) films were synthesized using sol-gel method and were then studied for the effects of 200 keV H+ ion implantation. The ion implantation caused a noticeable color change in the films and the larger spherulites broke up into smaller ones. Microstructural analysis revealed an increase in amorphous content and microscopic and vibrational spectroscopy showed the loss of crystalline nature upon irradiation. The effect of ion implantation on the electroactive phases and the non-polar a phase was discussed.
