“…3,4 In contrast to nonpolar fully fluorinated polymers, partially fluorinated polymers can be dissolved in polar solvents, such as organic esters and amines, and readily melt-processed by the standard method of molding and extrusion. 5 In particular, PVDF, with its high polarity, also possesses outstanding thermal, chemical, and mechanical stabilities, which has led to its widespread use in various applications, such as hybrid nanocomposite membranes, 6 electrochemically stable electrolytes for lithium batteries, [7][8][9] fuel cell membranes based on Nafion-PVDF blends, [10][11][12] and piezoelectric sensor materials utilizing its ferroelectric and pyroelectric properties. [13][14][15] Although PVDFbased materials serve as highly stable membranes, polymer electrolytes, and even sensor materials, the characteristic surface wettability of PVDF must be adequately understood to design next-generation PVDF-based materials and devices with enhanced performance.…”
