                         devices developed for the high power delivery require as 
                         supercapacitors the subject of intense research. Conductive 
                         polymers are a class of materials widely used in the development 
                         of supercapacitors. In particular, PANI is a promising polymer in 
                         electrode development due to its high specific capacitance, 
                         conductivity, flexibility, thermal stability, and low cost. Carbon 
                         felt fiber (CFF) is frequently used as a conductive substrate in 
                         the development of composites due to its physicochemical 
                         stability, good cost-benefit, and easy obtainability, being an 
                         excellent material for the preparation of devices of different 
                         shapes. In this work, composite electrodes were prepared by 
                         electrodeposition of PANI on CFF substrate according to a 
                         systematic study involving two different heat treatments, four 
                         synthesis times, and two molar proportions with the aid of the 
                         Kruskal-Wallis test to validate the importance of the variables 
                         concerning the specific capacitance and the mass of PANI 
                         deposited. The samples were characterized by physical-chemical 
                         instrumental techniques, for characterization of the local and 
                         crystalline structure, in addition to morphological analysis. 
                         Finally, the composites were evaluated using electrochemical 
                         techniques to analyze their performance in supercapacitor devices. 
                         Based on the analyzed data, it was found that all parameters are 
                         relevant for the optimization of the system in the preparation of 
                         materials with greater load storage capacity. Thus, among all the 
                         conditions, the specific capacitance that stands out the most is 
                         that obtained by the sample CFF 2000 2:1 1350s reaching the value 
                         of 303.76 F. g\−1.",
