Electrostrictive Energy Conversion of Polyurethane with Different Hard Segment Aggregations

Advances in Materials Science and Engineering, 2013
This work reported the electrostriction of polyurethane (PU) with different aggregations of hard segments (HS) controlled by dissimilar solvents: N,N-dimethylformamide (DMF) and a mixture of dimethyl sulfoxide and acetone denoted as DMSOA.

Dual‐Functional High‐Entropy Polymer Exhibiting Giant Cross‐Energy Couplings at Low Fields

Small Science
A key component of cooling devices is the transfer of entropy from the cold load to heat sink. An electrocaloric (EC) polymer capable of generating both large electrocaloric effect (ECE) and substantial electroactuation can enable EC cooling devices to ...

PROPIEDADES VOLUMÉTRICAS DE LA DL-ALANINA EN SOLUCIONES ACUOSAS DE TETRAFLUOROBORATO DE 1-BUTIL, 3-METILIMIDAZOLIO A DIFERENTES TEMPERATURAS

Química Nova, 2016
Densities of DL-alanine in aqueous ionic liquid, 1-butyl, 3-methylimidazolium tetrafluoroborate solutions were measured from 283.15 to 313.15 K. The densities measured were used to calculate apparent molar volumes (VΦ), apparent molar volume limits (VΦ0),

Electrostriction effect contribution for high dynamic range optical limiters

, 2012
[[abstract]]We show that electrostriction can dominate the nonlinear refraction in CS2 for nanosecond pulses. We use this effect in a new cascaded limiter geometry to make an extremely high performance optical limiter.

Electrostriction dynamics of blue phase II crystallites

, 1992
The dynamics of electrostriction occurring in the cubic blue phase BPII is investigated. We find that the lattice constants relax exponentially and that the time constants are independent of the electric field strength.

Challenges and opportunities in piezoelectric polymers: Effect of oriented amorphous fraction in ferroelectric semicrystalline polymers

Responsive Materials
Despite extensive research on piezoelectric polymers since the discovery of piezoelectric poly(vinylidene fluoride) (PVDF) in 1969, the fundamental physics of polymer piezoelectricity has remained elusive.

Applicability of the small anharmonicity approximation to electrostriction in Zr-doped ceria

Zr-Doped ceria exhibits electrostriction beyond the small-anharmonicity limit, with compressive stress-induced permittivity changes exceeding the zero-stress permittivity.

The correction of interferometric measurements of quadratic electrostriction for cross effects

, 1995
Electrostriction is the strain response of a dielectric material proportional to the square of an applied electric field. This effect is related to the strain-dependence of the dielectric function.
