Abstract:
The electrostriction effect of ferroelectric vinylidene fluoride (VDF) and
trifluoroethylene copolymers was studied by measuring their dimensional variation under an external electric field changing beyond a coercive electric field. The relationship between
strain and polarization for the copolymer which includes a 54 mol% VDF reveals a parabolic electrostriction relationship over the entire measurement range of the strain-polarization
relationship. The relationship for the copolymer which includes a 73 mol% VDF, however, deviates from the parabolic relationship. The result is discussed in terms of the
thermodynamics of a ferroelectric phase transition. Furthermore, the origin of the ferroelectricity of these copolymers is discussed.
