Fluorinated carbon polymer composites

A structure comprising a substrate formed from a dielectric material comprising:

• a composite of a fluorinated particulate carbon material dispersed in a polymeric material having a dielectric constant;
• said fluorinated carbon material being present in an amount sufficient for said composite to have a dielectric constant less than said dielectric constant of said polymeric material;
• said substrate including electrical conductor patterns;
• wherein said polymeric material is a thermoset, thermoplastic, or elastomeric polymeric material which is selected from the group consisting of polyimide, fluoropolymer, epoxy, polycyanurate, polysiloxane, polybenzocyclobutene, polyquinoxaline and bismaleimides;
• said structure further comprising a coupling agent in an amount sufficient to enhance the dispersability of said fluorinated carbon material in said polymeric material.
