In this study, the electrical conductivities and hydrophobic/hydrophilic properties of Polyacrylonitrile (PAN) + Polymethyl methacrylate (PMMA) composite nanofibers reinforced with nanowires were be investigated. The nanofibers are produced by the electrospin method. Their electrical conductivities and their hydrophobic/ hydrophilic properties were examined. The maximum the electrical conductivity value is 0.00298 S/cm at PAN + PMMA composite nanofibers with Ag nanowires (5 wt. %). The the biggest static contact angle occurred in PAN+PMMA composite nanofibers with 1 wt. % Ag nanowire. The static contact angles of all PAN + PMMA composite nanofibers with Ag nanowire were found to be bigger than those of PAN + PMMA composite nanofibers.
