Abstract:
1. A method for the preparation of functionalized particles, the method comprising: providing a feedstock at a first temperature, the feedstock comprising particles, exposing the feedstock to microwave radiation to heat the feedstock and react the particles with the surface treatment agent to provide the functionalized particles in less than about 60 minutes; wherein exposing the feedstock to microwave radiation occurs: (i) prior to combining the particles with an organic matrix; and (ii) in a closed reaction vessel; wherein the particles in the feedstock comprise silica particles and the surface treatment agent is selected from the group consisting of organosilanes, organotitanates, organozirconates, organoacids, organoamines, organothiols, phosphinic acids and combinations thereof; and wherein exposing the feedstock to microwave radiation heats the feedstock to a temperature of at least 130° C.
