STRUCTURAL PROPERTIES OF FERROELECTRIC POLYMERS (PVDF AND PTFE-42, SKF-32) AND COMPOSITES BASED ON IT
Some structural properties of ferroelectric polymer thin film samples of polyvinylidenefluoride, its copolymers (F-42, SKF-32) and its composites with ferrite powder were investigated. Infrared spectroscopy shows that film of SKF-32 does not have areas of VDF chains with long sequences in planar zig...

| Summary: | Some structural properties of ferroelectric polymer thin film samples of polyvinylidenefluoride, its copolymers (F-42, SKF-32) and its composites with ferrite powder were investigated. Infrared spectroscopy shows that film of SKF-32 does not have areas of VDF chains with long sequences in planar zigzag conformation. Evaluation of the effect of the ferrite particles on the polymer matrix shows, that filler promotes the formation of new crystallization nuclei in the polymer F-42 and PVDF (F2M). By using the methods of polarizing optical microscopy and laser light scattering it was revealed that the PVDF film obtained by hot pressing, have spherilitic supramolecular structure, whereas the samples prepared by precipitation from solution, do not have such structure. |
