Piezoelectric membranes for separation processes: Fabrication and piezoelectric properties

Journal of Membrane Science, 2013
Abstract Piezoelectric membranes were produced by “poling” prefabricated polyvinylidene fluoride (PVDF) membranes in an electric field. Scanning electron microscopy (SEM) studies revealed that electrical poling changed the microstructure of membranes significantly.

Piezoelectric Properties of 1-3 Piezoelectric Tubular Composites

Applied Mechanics and Materials, 2012
The piezoelectric coefficients of 1-3 piezoelectric tubular composites are studied. Taking into account the non-uniform electric field distribution in piezoelectric tube, the piezoelectric coefficients as functions of volume fraction, aspect ratio, tube density and matrix materials were discussed.

Structural Characteristics and Piezoelectric Properties of Electrospun Piezoelectric nanofibers

MRS Proceedings, 2005
ABSTRACTThis paper reports the development and characterization of PZT nanofibers with average diameters ranged from 50 to 150 nm for various sensing and actuation applications. PZT nano fibers have been developed by sol-gel electrospinning process. Both randomly distributed and uniaxially aligned PZT fibers were obtained from the sol-gel solution with

Piezoelectric and Electrostrictive Properties

1971
The piezoelectric and electrostrictive properties of crystals (particularly the former) have important practical applications. Piezoelectric crystals are so widely used in hydroacoustics, electroacoustics, communications, and measurement techniques that it is impossible to imagine the operation of many electrical and electronic devices and measuring ...

Piezoelectric Properties of Non‐Polar Block Copolymers

Advanced Materials, 2011
Most polymers are typical dielectric materials, but recent research in our group has shown that nanostructured block copolymer morphologies exhibit new and unexpected electroactive behavior. We present herein the fi rst study of converse piezoelectric properties in non-crystalline polymer systems, consisting of non-polar monomers, and evaluate its ...

Comments on Origins of Enhanced Piezoelectric Properties in Ferroelectrics

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009
This review discusses recent advances in understanding origins of large piezoelectric properties in some ferroelectric materials. In particular, it addresses the role of polarization rotation and monoclinic phases. It is suggested that the polarization rotation is an old concept that was proposed more than 30 years ago to explain enhanced properties of
