Electrospinning of Poly (ethylene-co-vinyl acetate)/Clay Nanocomposite Fibers
Poly(ethylene-co-vinyl acetate)/clay nanocomposite fibers were fabricated using electrospinning. The fiber diameters were controlled by varying the polymer/chloroform concentration, which resulted in fibers with diameters ranging from 1 to 15 {micro}m. The clay concentration was varied from 0.35 to 6.6 wt %. Scanning electron microscopy revealed that the fiber diameter increased with increasing clay concentration, whereas beading decreased. Transmission electron microscopy revealed a disruption of the spherulite structures by clay, which is consistent with heterogeneous nucleation. Shear modulus force microscopy indicated a reduction in melting point (T{sub m}) with decreasing diameter for fibers thinner than 15 {micro}m, which was confirmed by temperature dependent X-ray diffraction data. For fibers thinner than 8 {micro}m, the presence of clay further enhanced the reduction of T{sub m}.
