Description

This research aims to prepare the polyvinylidene fluoride-hexafluoropropylene (P(VDF-HFP)) fibers by electrospinning process with different electric fields. The aluminium chloride hexahydrate (AlCl$_3$.6H$_2$O) was filled into the fibers to act as nucleating agent for $\beta$ phase transformation. The morphology and phase transformation of the neat fiber mats with and without AlCl$_3$.6H$_2$O were investigated by scanning electron microscopy and Fourier infrared transformation. The results show that the average diameter of fibers decreases with increasing electric field. The diameter of composite fiber becomes smaller compared to that of the pure P(VDF-HFP) fiber. The $\beta$ phase fraction of fiber mats increases due to the applied electric field and AlCl$_3$.6H$_2$O filler. Moreover, an improvement of dielectric constant is found in the composite fibers, suggesting for mechanical sensors.
