In recent years, there has been a significant increase in textile production and, consequently, in the generation of waste. In Brazil alone, approximately 175,000 tons of this type of waste are generated, of which only 36,000 tons are reused. In this context, this work aimed to use textile waste as a base for conversion into conductive materials, adding value to a discarded material. To achieve this, the pyrolysis process was employed at high temperatures and in a controlled reducing atmosphere, generating a graphitic structure, as confirmed by techniques such as FTIR, TGA, Raman Spectroscopy, XRD, and TEM. Additionally, contact angle measurements were performed to determine the material's wettability with water, resulting in an average angle of 118°, demonstrating hydrophobic characteristics typical of graphitic structures with sp² bonds. The surface area of the synthesized material was determined using BET adsorption isotherms, revealing the formation of a material with a high surface area, with an average value of 433 m²/g. This is a highly desirable feature for applications in electrochemical devices, combined with an electrical conductivity of 3.17 S/cm, as measured by four-point probe resistivity tests. Based on the results obtained so far, the developed material shows promise for application in high-performance electrochemical devices.
