Latest Patents

Ziyang Chang holds a patent for the "Preparation method of double-layer carbon-paper base paper with high uniformity and gradient pores." This patent discloses a method that involves adding carbon fibers to an alkali lignin aqueous solution for treatment. The process controls the alkali lignin aqueous solution to reach subcritical water conditions, modifying the carbon fibers with sodium phenol reactive groups. This modification improves the hydrophilic groups on the surface of the carbon fibers and enhances their surface rough structure. Furthermore, the method produces carbon nanotube clusters on the surface of the carbon fibers, resulting in surface-thermally-modified carbon fibers. These fibers are then added to a dispersant for dispersion, mixed with auxiliary materials, and prepared into carbon-paper base paper through a wet forming process. Ziyang Chang's innovative patent represents a significant advancement in the production of high-quality carbon-paper materials.
