Piezoelectric membranes for separation processes: Fabrication and piezoelectric properties

► Method for fabrication of novel anti-fouling piezoelectric membranes is described. ► Poling in an intense electric field was used to impart piezoelectric properties to PVDF membranes. ► Crystalline and microstructure of PVDF were changed during poling process. ► Poled membranes were able to generate electric signal when subjected to mechanical deformations.► When energized by an AC signal, these membranes were vibrating as detected by a laser vibrometer.
