| titleOfInvention | Polymer-ceramic core-shell particle powder, and manufacturing processes and articles comprising the powder |
| abstract | Ceramic-polymer composites and methods. The ceramic-polymer composite in powder and/or pellet form may include a plurality of core-shell particles, each core-shell particle comprising a core and a shell around the core; A core comprising a ceramic selected from the group of ceramics comprising: Al 2 O 3 , Fe 2 O 3 , ZnO , ZrO 2 , and SiO 2 ; A shell comprising a polymer selected from the group of polymers comprising: polycarbonate (PC) copolymers, polyetherimide (PEI), polyetherimide (PEI) copolymers, poly phenylsulfone (PPSU), polyarylethersulfone (PAES), and polyether sulfones (PES); In powder form, the core-shell particles are in substantially dry powder form with a moisture content of less than 2% by weight. In pellet form, the shells of adjacent core-shell particles are joined to prevent segregation of adjacent core-shell particles and deformation of each pellet. A method of forming a ceramic-polymer composite includes: superheating a mixture of a polymer, a solvent, and a ceramic to dissolve the polymer in the solvent; agitating the superheated mixture while substantially maintaining the mixture at elevated temperature and pressure; and cooling the mixture to cause the polymer to precipitate on the ceramic particles, thereby forming a plurality of polymer-ceramic core-shell particles of the present invention. A method of forming a part comprises applying a first pressure to a powder of polymer-ceramic core-shell particles of the present invention substantially filling a mold while the powder is at or above a first temperature above a melting temperature (Tm) of the polymer. include |
