Surface hydrophilizing treatment
Atmospheric plasma is used to hydrophilically modify the surface of carbon felts and can be applied to large areas of the material. In this way, oxygen-containing functional groups (e.g., carboxyl and hydroxyl groups) can be introduced to the surface without destroying the structure of the material, thereby improving its compatibility and adhesion to hydrophilic, electrolyte, or other materials.(math.) genusIt is more effective in subsequent processing.
