Abstract(s)Electroactive macroporous poly[(vinylidene fluoride)-co-trifluoroethylene] mambranes membranes have been processed by solvent evaporation at room temperature with different polymer/solvent concentrations. The pore architecture consists of on an interconnected spherical pores and this morphology is independent of the membrane thickness. The porosity of the produced membranes increases from 57% for the higher polymer concentration in the polymer/solvent solution (15/85), up to 83% for the lowest polymer amount in the polymer/solvent solution. Far infrared and differential scanning calorimetry measurements reveal that the polymer crystallizes in the ferroelectric phase and the polymer/solvent ratio does n’t not changes the Curie transition and the melting temperature of the polymer.
