Polyvinylidene fluoride–trifluoroethylene as a reservoir for absorbed water

The absorption of water in Langmuir–Blodgett fi lms of ferroelectric copolymers of polyvinylidene fl uoride with trifl uoroethylene is shown to depend upon the fi lm thickness. This water absorption can have a profound effect on the dielectric properties of the copolymer fi lms.

Universal Ferroelectric Switching Dynamics of Vinylidene Fluoride-trifluoroethylene Copolymer Films

In this work, switching dynamics of poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer films are investigated over unprecedentedly wide ranges of temperature and electric field. Remarkably, domain switching of copolymer films obeys well the classical domain nucleation and growth model although the origin of ferroelectricity in organic ferroelectric materials inherently differs ...

Effects of an external electric field on the ferroelectric-paraelectric phase transition in polyvinylidene fluoride-trifluoroethylene copolymer Langmuir-Blodgett films

Enhance the Pyroelectricity of Polyvinylidene Fluoride by Graphene-Oxide Doping

The high quality properties and benefits of graphene-oxide have generated an active area of research where many investigations have shown potential applications in various technological fields. This paper proposes a methodology for enhancing the pyro-electricity of PVDF by graphene-oxide doping. The PVDF film with graphene-oxide is prepared by the sol-gel method. Firstly, PVDF and graphene-oxid...
