Abstract: Disclosed is a composite from about 50 wt. % to about 90 wt. % of a thermoplastic resin, wherein the thermoplastic resin comprises a polycarbonate polysiloxane copolymer; and from about 10 wt. % to about 50 wt. % of a carbon-based filler. The composite exhibits a dielectric constant ε′ of between 5 and 20 and a dissipation loss ε″ of between 0.1 and 6, measured at frequencies between about 10 and 120 GHz.
