摘要：

In the presence of an electrical field, the mechanical behavior of thin films of copolymer of vinylydene-fluoride and trifluoroethylene varies with the annealing temperature. If the film is annealed below the melting point of the copolymer, we observe, before any poling, an electrostriction effect mixed with a piezoelectric one. If the film is annealed above the melting point we observe only an electrostriction effect before the poling and a piezoelectric one after. The high value of the electrostriction coefficient obtained before poling could be used for actuators application. © 1995 American Institute of Physics.
