摘要： The invention relates to a composition comprising a blend of fluorinated electroactive polymers and having a dielectric permittivity that exhibits greater stability over the operating temperature range with respect to each polymer employed on its own. The invention also relates to formulations and films produced on the basis of said composition. The invention also relates to a field-effect transistor, at least part of the dielectric layer of which is composed of a blend of fluorinated electroactive polymers.

摘要： A composite article including at least one electronic system, integrated onto the surface or in the volume of a thermoplastic matrix. The electronic system includes at least one piezoelectric transducer and means for transmitting an electrical signal. The piezoelectric transducer includes a piezoelectric polymer essentially consisting of, or consisting of, repeating units derived from vinylidene fluoride (VDF) and vinylidene trifluoride (TrFE), the molar proportion of the unit derived from TrFE being from 15% to 50% relative to the total number of moles of the units derived from VDF and TrFE. Also, the use of the electronic system and to the use of the article.
