Electrospinning of Neat and Laponite Nanoclay-filled Poly (Vinylidene Fluoride)
In this manuscript, wet-electrospinning method was used to electrospin poly (vinylidene fluoride) (PVDF) into nanofibrous membranes from its dimethylformamide (DMF) solutions. Here a water bath was used as the coagulation bath to prevent the PVDF nanofiber re- melt, which occurred while solid collector was applied. On the other hand, to prevent PVDF nanofiber re-melt, laponite nanoclay was incorporated into PVDF solutions to improve the electrospinnability without using liquid coagulation bath as well as to enhance the physics properties of PVDF nanofibrous membranes. The results of transmission electron microscopy (TEM) showed that nanoclay platelets were well dispersed in fiber matrix. Thermal gravimetric analysis (TGA) and mechanical property test results indicated that both the thermal stability and mechanical strength of the PVDF electrospun membrane were improved through the incorporation of nanoclay in polymer fiber.
