Solution blow spinning (SBS) is a spinning technique for fabricating the sub-micron fibers by utilizing air pressure. Unlike the electrospinning, almost all materials can be spun due to conductivity is not required in the base material. Further advantages of this process are a simple process and low initial cost. In this study, we focused on preparing mechanically tough and flexible nanofiber web using polyurethane (PU) incorporating thin multi-walled carbon nanotube (T-MWNT) by SBS. The effect of the incorporation of T-MWNTs on the morphological, electrical and mechanical properties of PU/T-MWNTs nanofiber webs was investigated.
