Electro-mechanical properties of the piezoelectric polymer PVDF
TLDR
In this article, a consistent experimental program has been developed to investigate the mechanical and electrical properties of polyvinylidene fluoride (PVDF), and the results of the study indicate that this piezoelectric polymer can be characterized as an orthotropic, thermorheologically simple material with constant PDE strain coefficients over the experimental range of stresses, frequencies and temperatures.Abstract:
A consistent experimental program has been developed to investigate the mechanical and electrical properties of polyvinylidene fluoride (PVDF). The results of the study indicate that this piezoelectric polymer can be characterized as an orthotropic, thermorheologically simple material with constant piezoelectric strain coefficients over the experimental range of stresses, frequencies and temperatures. The mechanical properties of PVDF are time-dependent and, under certain loading and temperature conditions, can be treated using the principles of linear hereditary viscoelasticity.read more
