Abstract:
Unique highly porous Polyvinylidene difluoride (PVDF) nanofibers (Figure 1) of about 50-500 nm in diameter were prepared by electrospinning. Electrospinning setup (Figure 2) allows us to control the nanofiber placement on the gap-type electrodes. In fact, the produced nanofiber arrays and yarns are free suspended in the gap between the electrodes. The main advantage of this top-down electrospinning nanomanufacturing technology is its relatively low cost compared to the synthetic bottom-up method. The PVDF yarns have high tenacity, can be bent, knotted, or twisted without any breakage. DSC, TGA, and FTRI characterization of the produced yarns show the presents of crystalline PVDF -phase that is responsible for piezoelectric properties of PVDF materials. Mechanical properties and adsorption capability of single nanofiber have been studied using atomic force microscopy (AFM).
