A composite particle includes a discrete, hollow, ceramic spheroid and a fluoropolymer layer disposed thereon. The fluoropolymer is a homopolymer or copolymer of a perfluoroalkyl vinyl ether; a perfluoroalkoxy vinyl ether; at least one fluoroolefm independently represented by formula C(R)2=CF-Rf, wherein Rf is fluorine or a perfluoroalkyl having from 1 to 8 carbon atoms and R is hydrogen, fluorine, or chlorine; or a combination thereof. Methods of making the composite particles, composite materials, and articles including them are also disclosed.
