Controlling dielectric loss and ionic conductivity through processing optimization of electrostrictive polymers

Reducing leakage current and dielectric losses of electroactive polymers through electro-annealing for high-voltage actuation

“…6 Of the existing dielectric EAPs (silicones, acrylates, polyurethanes and PVDF-based polymers), the most performing one in terms of electromechanical conversion is uorinated electrostrictive terpolymer P(VDF-TrFE-CTFE). [7][8][9][10] The small value of Young's modulus of silicones and acrylates such as polydimethylsiloxane (PDMS) and polyurethane (PU) allows these polymers to reach very large strains. 11 At the same time, it severely limits the electro-to-mechanical energy conversion.…”
