Activated carbon fibers were obtained through electrospinning method and activation process for the gas sensor. The surface morphology was investigated by using FE-SEM and their pore structure was studied by using BET apparatus. The electrical conductivity was calculated by using four-probe method. The electrical response to the gas was tested by using Keithely 2400 (DC, Bias vaoltage source, current measure application). Due to the high specific surface area and excellent electrical conductivity intrinsically associated with these nanoscale functional polymer fibers, we achieved significantly enhanced sensitivity for the nanofiber sensors. |
