Abstract
Polymer-ceramic composite articles with relatively low dissipation factor (Df) and relatively high dielectric constant (Dk), as well as polymer-ceramic core-shell powders and pellets adapted for making such composite articles. The ceramic-polymer composites, in powder and/or pellet forms, comprise 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 that is selected from the group of ceramics consisting of: BaTiO3, SrTiO3, TiO2, CaTiO3, MgTiO3, and combinations of any two or more thereof; and the shell comprises a polymer selected from the group of polymers consisting of: polyetherimide (PEI), polyetherimide (PEI) copolymers, polyphenylene ether (PPE), polyphenylene sulfide (PPS), polyaryl ether ketone (PAEK), polypropylene (PP), polytetrafluoroethylene (PTFE), perfluoroalkoxy alkane (PFA), fluorinated ethylene propylene (FEP), ethylene tetrafluoroethylene (ETFE), polyvinylidene fluoride (PVDF), and ethylene chlorotrifluoroethylene (ECTFE).
