Synthesis of CNF using electrospinning is an important part of this research, the synthesis process plays an important role in the quality of the CNF produced. In addition, the results of characterization of the different morphological structures of the CNFs formed show different properties, so that surface modification can help make CNF compatible for various applications. The characterization results show that the electrospinning result of the CNF composite diameter is in the range 200–450 nm, this shows that the electrospinning process with a rotating drum collector has advantages compared to a stationary plate type collector. Based on the electrical properties of the CNF I-V meter measurement results, a good conductivity value is obtained, which is due to the larger surface area of the CNF making it easier for electrons to move freely, so that CNF has the potential to be a good and modern sensor material. Whereas from the capacitive properties measured by the cyclic voltammogram (CV) curve with 5 mV/s and a measuring temperature of 25 °C shows the ideal behavior of the capacitor, the ideal CV curve with an almost square shape at different scanning sweep rates, so the use of CNF as a capacitive electrode is proper application.
