This study focuses on presenting the optimal electrospinning conditions of producing uniform nanofibers using polyamide 6,6 (PA66) solution with enhanced electrical conductivity. To enhance the conductivity, an organic salt, benzyl trimethyl ammonium chloride (C10H16ClN, BTMAC), was added to PA66 solution. When no salt was added to the PA66 solution, the uniform nanofibers were electrospun only at limited conditions, such as flow rate of 0.5 mL/h and electric fields greater than 2.0 – 3.5 kV/cm. In contrast, by the addition of BTMAC, range of optimal conditions for uniform nanofibers was expanded; uniform nanofibers were obtained at flow rate of 0.5 – 1.5 mL/h and electric fields greater than 1.3 – 1.6 kV/cm. This means that the electrospinnability of the nanofibers is improved by increasing electrical conductivity of the solutions. Furthermore, the addition of BTMAC affected the increasing of number average diameters and standard deviation of the nanofibers. |
