Abstract: Electrospun Polyurethane nanofibrous webs were produced from the solutions prepared with various volume ratios of N,N-dimethylformamide (DMF) and Tetrahydrofuran (THF). Characteristics of the blended solutions were explored in terms of viscosity and conductivity. Morphologies of nanofibrous webs were observed by SEM analysis. Experimental results exhibited that the morphologies of polyurethane nanofiber webs have been changed significantly with the solvent selection and mixing ratios of the solvents during electrospinning. Diameter of the nanofibers was ranged between 277 nm and 556 nm, respectively. Tensile strength and elongation measurements proved that mechanical properties of the nanofibrous webs were remarkably influenced by the fiber morphology and the uniformity.
