Various polyblends of polyurethane(PU) and polysulfone(PSF) dissolved in a mixture of tetrahydrofuran(THF) and N,N-dimethylformamide(DMF) were produced by electrospin- ning, in different ratios, using several electrospinning conditions and the relationship between morphology and mechanical behavior of the resulting fiber web was examined in detail. Surface tension, viscosity and electrical conductivity of polymer solutions affecting electrospinning were measured, scanning electron microscopy(SEM) and tensile properties investigated.
