It is a composite particle containing a separable hollow ceramic spheroid and a fluoropolymer layer disposed thereon. The fluoropolymer can be a homopolymer or a perfluoroalkyl vinyl ether, a perfluoroalkoxy vinyl ether, at least one fluoroolefin (independently represented by the formula C (R) 2 = CF-Rf, where Rf is fluorine, or 1 Perfluoroalkyl having ˜8 carbon atoms, R is hydrogen, fluorine, or chlorine) or a mixture of these. Also disclosed are methods for making these composite particles, composite materials, and articles comprising them. |
