1. A synthetic functionalized additive comprising:
a layered magnesium silicate, the layered magnesium silicate comprising:
a first functionalized silicate layer comprising a first tetrahedral silicate layer covalently bonded to at least two different functional groups,
an octahedral brucite layer, the octahedral brucite layer comprising magnesium, and
a second functionalized silicate layer comprising a second tetrahedral silicate layer covalently bonded to at least two different functional groups,
where the octahedral brucite layer is positioned between the first functionalized silicate layer and the second functionalized silicate layer;
where the at least two different functional groups covalently bonded to the first tetrahedral silicate layer have different chemical structures from one another; and
where the at least two different functional groups covalently bonded to the first tetrahedral silicate layer are the same or different than the at least two different functional groups covalently bonded to the second tetrahedral silicate layer.
