In this study, we fabricated highly conducting fiber using conducting fillers by wet spinning. Polyacrylonitrile (PAN) was used as the fiber forming polymer. Two-dimensional copper dendritic particle coated with silver (Ag-Cu dendrimer) was used as the conducting fillers. To prepare spinning solution, PAN (20 wt%) was first dissolved in DMF and conducting fillers were then uniformly dispersed in the polymer solution using a Thinky mixer. Coagulation was performed in DMF and water mixture (6:4 by volume) at 60 ºC and the fiber draw ratio was in the range of 1 to 3. The electrical conductivity of PAN fiber as high as 1,034 S/cm. |
