Pyroelectric effect and piezoelectric properties of composites based on ferroelectric copolymer of poly(vinylidene fluoride-trifluoroethylene) and deuterated triglycine sulfate

Abstract

In this work, composite films of a copolymer of vinylidene fluoride with trifluoroethylene P(VDF-TrFE) comprising microcrystals of deuterated triglycine sulfate (DTGS) were produced. The pyroelectric properties of the composite samples were studied by the dynamic method. Pyroelectric measurements indicated an extreme dependence of the pyroelectric coefficient on the concentration of DTGS inclusions in the composite. Piezoelectric modules were macroscopically measured in static mode. The measured piezoelectric moduli d₃₁ and d₃₃ show ambiguous dependences on the volume fraction of DTGS inclusions.
