Impact of the uniaxial mechanical extension on the phase transmutations in the polyvinylidene fluoride films

The authors analyze the modification of the x-ray diffractive and infrared spectra of polyvinylidene fluoride films during the uniaxial mechanical extension. They prove that the sample amorphisation, delusion of the б-phase and densification of the Я-phase take place during the uniaxial tension of the PVDF while the space of the CH belt can be a normalization parameter during the quantitative analysis of the IR-spectra samples which differ in their square from the one of the analyzing surface.
