Abstract

A multi-functional silsesquioxane, method of making the same, and coatings incorporating the same, including a polyhedral silsesquioxane including at least one first face and at least one second face that is spaced apart from the at least one first face; at least one first functionality bonded to the at least one first face; and at least one second functionality different from the first functionality, and being bonded to the at least one second face. In one particular respect, silica for the silsesquioxane may be derived from rice hull ash via an octa(tetramethylammonium)silsesquioxane octaanion.
