Effect of phase transitions on the kinetic parameters of polytetrafluoroethylene deformation
V. M. Egorov, P. N. Yakushev Ioffe Institute, St. Petersburg
Abstract:
The effect of solid-state phase transitions on the kinetic parameters of creep deformation in polytetrafluoroethylene has been studied by differential scanning calorimetry and a laser-interferometric creep rate meter. It has been shown that the deformation activation volumes and the elementary phase transition volume differ from each other by more than an order of magnitude. The crystalline component of this polymer becomes a liquid-crystal phase coexisting with an amorphous phase.
