Nanofber mats of poly(ε-caprolactone)/nanoclay nanocomposites were fabricated by electrospinning. The effects of the solution concentration and the nanoclay content of nanocomposite materials on the fnal nanofber structure were investigated. Morphology and diameter of the nanofbers were studied using optical and scanning electron microscope. It was observed that the poly(ε-caprolactone) at concentration of 5% to 8% could be electrospun into the fbrous structure. The results showed that the presence of the nanoclay promoted the creation of fbrous structures in comparison with the poly(ε-caprolactone) without nanoclay. On the other hand, increasing the nanoclay content resulted in a lower average fber diameter. Shear viscosity and conductivity of the solutions were also reported. The presence of nanoclay increased conductivity and shear viscosity of the solutions. Formation of the nanofbers and decrease in their diameters are discussed on the basis of shear viscosity and conductivity of electrospun solution. This electrospun nanofber could be used for tissue engineering application.
