Equations of State for Poly(vinylidene fluoride) [PDF]

Polymer Journal, 1982
Equations of state were determined separately for the crystalline and amorphous parts of Form I and II samples of poly(vinylidene fluoride), assuming a linear relation between the specific volume and the degree of crystallinity. The compressibility data of Form II bulk samples were obtained by dilatometry, and those of the Form I and II crystals were ...

Photovoltaic Effect in Poly(vinylidene fluoride) [PDF]

Polymer Journal, 1981
The generation of photocarriers and their transport processes in poled poly(vinylidene fluoride) films under light illumination are discussed from the viewpoint of a ferroelectric property of β form crystals. We observed not only a pyroelectric current but an additional current due to anomalous photovoltaic effect.
