Abstract:
A hybrid carbon black is provided, which includes a carbon black core and a polymer film wrapping an entire surface of the carbon black core. The polymer film includes a network of a plurality of polymer main chains crosslinked each other, and a plurality of dispersion-side chains bonded to the polymer main chains. The dispersion-side chains come from an acrylate monomer with a chemical structure of: wherein when n is 4 to 7, R1 is H or CH3, and when n is 8 to 14, R1 is CH3.
Abstract:
A hybrid carbon black, a coating composition, and a shielding material employing the same are provided. The hybrid carbon black includes a core of carbon black, and a cross-linked network polymer film covering the whole surface of the carbon black overall. In particular, the carbon black core has a mass fractal dimension between 2 and 3 and a surface fractal dimension between 2 and 2.5, and the cross linking network polymer film includes a product obtained by crosslinking a composition including a styrene monomer and a divinylbenzene monomer.
