Abstract
Ceramic-polymer powders comprising a plurality of core-shell particles, where: each of the core-shell particles comprises a core and a shell around the core; the core comprises a ceramic selected from the group of ceramics consisting of: Al2O3, Fe2O3, ZnO, ZrO2, and SiO2; and the shell comprises a polymer selected from the group of polymers consisting of: PC copolymers, polyetherimide (PEI), polyetherimide (PEI) copolymers, polyphenyl sulfone (PPSU), polyarylethersulfone (PAES), and poly ether sulfones (PES). In powder form, the core-shell particles are in a substantially dry powder form having a moisture content of less than 2% by weight.
