Abstract

See full text

A method for preparing composites of polymer and fly ash particles, wherein the fly ash particles contains heterogeneous compositions of carbon and metal oxides, the method including: the steps of mixing the fly ash particles and an aqueous coating solution, including: a coating component selected from the group consisting of monomers, oligomers, pre-polymers, polymers, and combinations thereof, and an aqueous solvent serving to dissolve the coating component; and, while performing the step of mixing, initiating polymerization or crosslinking or both polymerization and crosslinking of the coating component to at least partially coat the fly ash particles with polymer or a crosslinked polymer network that agglomerates the fly ash particles and coats the surface of the fly ash particles, wherein the polymer or crosslinked polymer network formed in the step of initiating is hydrophobic.
