1. A coating composition comprising:
an aqueous media; silica nanoparticles dispersed in the aqueous media, wherein the silica nanoparticles have an average particle size in a longest dimension of up to 100 nm; and clay particles dispersed in the aqueous media, wherein the clay particles have an average particle size in a longest dimension in a range from 20 nm to 1000 nm; wherein a weight ratio of the clay particles to the silica nanoparticles is in a range from 0.01 to 0.25, and wherein the coating composition has a pH of less than or equal to 4. |
