Patent ID: 8741432

Claim:
A treated aggregate, comprising: a) an inorganic oxide substrate having the formula SiO x , wherein the inorganic oxide substrate possesses a specific surface area of at least 50 square meters per gram; b) a molecular layer coating of —CF 3 terminated molecular fragments, wherein the —CF 3 terminated molecular fragments are covalently bonded to the inorganic oxide substrate such that at least 15 parts by weight of fluorine in the form of —CF—, —CF 2 —, or —CF 3 fragments is covalently bound to 100 parts by weight of the inorganic oxide substrate, wherein the treated aggregate comprises a geometric shape that is determined by the inorganic oxide substrate and the molecular layer coating, the geometric shape being characterized by an occurrence of concave features of multiple sizes spanning a range from about 5 nm to about 0.001 mm.
