Poly(ε-caprolactone) (PCL) is semi-crystalline polyester which is compatible with various polymers. Thermoplastic polyurethane (TPU) has been growing interest in engineering materials fields because of its properties of both rubber and plastics, including excellent abrasion resistance. In this study, various polyblends of PCL and PU dissolved in a mixture of tetrahydrofuran and N,N-dimethylformamide were produced webs by electrospinning. Each weight ratio of PCL/PU polyblends was 100/0, 70/30, 50/50, 30/70, and 0/100. Viscosity and electrical conductivity of polymer solutions affecting in electrospinning were measured. The scanning electron microscopy(SEM) along with a universal testing machine (UTM) was used to analyze the relationship between morphology and mechanical behavior of the resulting webs.
