Our final goal is to make the metal nanofibers having good properties of metal and explore the mechanical properties of metalized single nanofibers. We are expecting that they would be strong like general metals. In our previous study, we were successfully prepared metallized nanofiber webs by using a combined technique of electrospinning and metallization. It was found that the metallized nanofiber webs exhibited higher mechanical properties and enhanced surface resistivity depending on the thickness of the deposited metallic layers. However, evaluating the mechanical properties for the nanofiber webs had remained lots of problems to be figured out. Therefore, in this study, we developed the tensile test machine and the mechanical properties of metallized single PU nanofibers were investigated by using that tensile test machine. Metallized single PU nanofiber was successfully prepared by a combined technique of electrospinning and metallization. The tensile strength of 50nm Cu-metallized PU single nanofiber (~ 338 MPa) was clearly higher than that of pure PU single nanofiber (~ 132 MPa), whereas the Young’s modulus of 50nm Cu-metallized PU single nanofiber was a little smaller than that of pure PU single nanofiber, suggesting the incomplete metal coating.
