  • the carbon black may first be dispersed in an aqueous medium in the presence of nonionic surfactants and/or anionic polymers before addition to a slurry containing the platy substrate. Without the dispersion of the carbon black, the carbon black may have a tendency to agglomerate and not deposit on the substrate when the hydrous or hydroxide precipitate is formed. Thus for example, the carbon black may be in a dispersed form when combined with the platy substrate before precipitation with the polyvalent cation onto the substrate.
  • wt. % refers to an amount of loading of a material versus a starting substrate onto which the material is loaded. For example, 5 wt. % of carbon black would correspond to 5 g of carbon black loaded onto 100 g of platy substrate.
