Fabrication of poly (vinylidene fluoride) films by ultrasonic spray coating; uniformity and piezoelectric properties

[Display omitted] •Ultrasonic spray coating system is used for fabrication of pure PVDF films with high piezoelectric coefficient (d33 = 48 pm/V).•Highly crystalline (56%) PVDF films with predominant β phase for flexible and transparent engineering devices are achieved without post processing.•Unifo...
