Electrospun nanofibers with piezoelectric properties [PDF]

2015 IEEE Electrical Insulation Conference (EIC), 2015
This paper presents a preliminary comparison between the piezoelectric behavior of PVdF electrospun nanofibrous membranes and a commercial PVdF film. XRD measurements showed that the β phase of the realized electrospun PVdF membranes is much larger than that of the PVdF film here considered.

3D Printing and processing of miniaturized transducers with near-pristine piezoelectric ceramics for localized cavitation

Nature Communications, 2023
The performance of ultrasonic transducers is largely determined by the piezoelectric properties and geometries of their active elements. Due to the brittle nature of piezoceramics, existing processing tools for piezoelectric elements only achieve simple ...

Piezoelectric Enhancement of Piezoceramic Nanoparticle-Doped PVDF/PCL Core-Sheath Fibers

Nanomaterials, 2023
Electrospinning is considered to be an efficient method to prepare piezoelectric thin films because of its ability to transform the phase of the polymers. A core-sheath structure can endow fibers with more functions and properties.
