•Novel multifunctional membranes have been developed.•The membranes are based on CoFe2O4 nanoparticles and P(VDF-TrFE).•The membranes show magnetic, piezoelectric and magnetoelectric response.•This multifunctional membrane allows sensor and actuator functionalities.
Novel multifunctional porous films have been developed by the integration of magnetic CoFe2O4 (CFO) nanoparticles into poly(vinylidene fluoride)-Trifuoroethylene (P(VDF-TrFE)), taking advantage of the synergies of the magnetostrictive filler and the piezoelectric polymer. The porous films show a piezoelectric response with an effective d33 coefficient of −22 pC/N−1, a maximum magnetization of 12 emu g−1 and a maximum magnetoelectric coefficient of 9 mV cm−1 Oe−1. In this way, a multifunctional membrane has been developed suitable for advanced applications ranging from biomedical to water treatment.
