At higher strain, carbon fibers almost entirely occupy the interfibrous void space in carbon felt, leading to a much more compact structure. This compactness inhibits further elastic deformation of the fibers, highlighting the material’s robustness in various applications, including the Electro-Fenton process for energy and depollution.
Carbon felt, a porous and flexible material, is a key component in thermal insulation. The most notable thermal insulation materials are porous fibers/ceramics, aerogels, and carbon-carbon (C/C) composites. Carbon felt’s unique properties, such as hydrophilicity and conductivity, make it ideal for various energy applications.
In the Electro-Fenton process, porous carbon felt (PWE) was polarized to facilitate oxygen reduction, while simultaneously, the SSE (Solid State Electrolyte) oxidized H2O2, a method effective in detecting hydrogen peroxide production. Moreover, the advancement in carbon felt-based electrodes, notably in redox reactions of vanadium ions, showcases its superior electrochemical activity and electronic conductivity.
Carbon felt is not just limited to thermal insulation but also extends its utility to biological cathodes in Microbial Fuel Cell (MFC) technology. This includes forms like carbon cloth and carbon brushes, known for their high specific surface areas and strong power outputs. The electroconductive carbon felt, with its permeable structure, is extensively used in electrochemical applications like redox flow batteries and fuel cells.
