COMPOSITE PARTICLES INCLUDING A FLUOROPOLYMER, METHODS OF MAKING, AND ARTICLES INCLUDING THE SAME |
| 摘要 |
A composite particle includes a discrete, hollow, ceramic spheroid and a fluoropolymer layer disposed thereon. The fluoropolymer is an amorphous homopolymer or copolymer of a perfluoroalkyl vinyl ether; a perfluoroalkoxy vinyl ether; at least one fTuorookfe 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. |

1. A composite particle comprising:
a discrete, hollow, ceramic spheroid, and a layer of amorphous fluoropolymer disposed on the discrete, hollow, ceramic spheroid, wherein the amorphous fluoropolymer is an amorphous homopolymer or copolymer of a perfluoroalkyl vinyl ether; a perfluoroalkoxy vinyl ether, at least one fluoroolefin 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. |
