Polymorphism Control of Poly(vinylidene fluoride) through Electrospinning

Abstract Polymorphism control of PVDF has been realized through electrospinning. PVDF fibrous membranes with fiber diameter in the range of 100 nm to several micrometers were produced by electrospinning and the crystal phase of electrospun PVDF fibers can be adjusted at the same time. Through the control of electrospinning parameters such as the solvent, electrospinning temperature, feeding rate, and tip‐to‐collector distance, PVDF fibrous membranes containing mainly α ‐ or β ‐ or γ ‐phase could be fabricated successfully. magnified image
