Influence of the PAni morphology deposited on the carbon fiber: An analysis of the capacitive behavior of this hybrid composite

AbstractCF/PAni composites were synthesized using the polymerization chemistry. Three different deposition times were used in the synthesis, such as: 30, 60 and 90min. The morphology and the structure of composites were analyzed by SEM and Raman spectroscopy, respectively. The influence of the mass of polymer deposited on the carbon fiber, with respect to the values of specific capacitance (Csp) was analyzed by electrochemical experiments. The optimum value of the Csp was obtained for CF/PAni-30min (Csp=188Fg−1). This fact is related to the lower charge transfer resistance, due to its more homogeneous morphology and thin layer polyaniline
