Hydroxylated carbon black

Product Name Hydroxylated carbon black Product Overview Hydroxylated conductive carbon black is a functionalized material obtained by surface modification of ordinary conductive carbon black, introducing hydroxyl (-OH) functional groups onto its surface. The incorporation of hydroxyl (-OH) groups significantly enhances the hydrophilicity of the conductive carbon black and its dispersibility in polar systems. Its core value lies in the fact that the surface hydroxyl groups can form stronger interfacial interactions, such as hydrogen bonds, with the polar groups of polymer matrices (such as polyolefins, fluororubber, natural rubber, etc.). This not only improves the uniform dispersion of the conductive filler in the matrix, facilitating the formation of a more complete conductive network, thereby endowing the composite material with superior and stable conductivity or antistatic properties, but also enhances the interfacial bonding between the filler and the matrix, positively impacting the mechanical properties (such as strength) of the composite material. Technical Parameter Appearance:Black powder BET:~ 96 m2/g Grain size:30-45nm Content:~5.5% XPS-Peak-Differentation-Imitating Analysis Product Features 1)High specific surface area and surface activity: Hydroxyl groups (-OH) are introduced on the surface, providing a large number of active sites and adsorption sites, which greatly enhances hydrophilicity and polarity and significantly reduces the tendency of particle agglomeration. 2)Stable Electrical Conductivity: The modification process completely retains the original conductive network structure, and the hydroxyl groups promote the formation of a more complete conductive pathway for the filler in the matrix. Strong Interfacial Bonding Force: The surface hydroxyl groups can form strong interactions such as hydrogen bonds with the polar groups of the polymer matrix, enhancing the interfacial bonding force between the filler and the matrix. Application Fields 1)Water-based Conductive Coatings and Inks: Suitable for water-based systems (e.g., water-based polyurethane, acrylic coatings). Due to the surface hydroxyl groups that enhance hydrophilicity and dispersion stability, it can be used to prepare antistatic floor paints, conductive coatings for electronic device housings, conductive packaging inks, etc., solving the problems of traditional carbon black such as easy agglomeration and uneven color development in water-based systems. 2)Conductive Rubber and Plastic Products: Suitable for substrates such as polyolefins, fluororubbers, and natural rubbers. It can be used to produce antistatic products including conductive rubber seals, antistatic plastic housings, and antistatic conveyor belts for coal mines, while enhancing the mechanical strength of rubber and plastic products. 3)Cable Shielding Materials: Used as a filler for the shielding layer of high-voltage cables and communication cables. Hydroxyl groups promote the formation of a uniform conductive network of carbon black in matrices like cross-linked polyethylene and polypropylene, improving shielding efficiency. Meanwhile, they enhance the interfacial bonding force between the filler and the matrix, boosting the aging resistance and mechanical properties of the cables. 4)Energy Storage Field: Serves as a conductive additive for electrodes of lithium-ion batteries and supercapacitors. Its high specific surface area and surface active sites can improve the electron transfer efficiency of the electrodes. The hydroxyl groups form hydrogen bonds with electrode active materials (e.g., ternary materials, activated carbon), enhancing the structural stability and cycle life of the electrodes. 5)Conductive Adhesives and Sealants: Applied in polar adhesive systems such as epoxy resins and silicones to achieve conductive bonding of electronic components and electromagnetic shieding sealing.
