CIRCUIT MATERIALS, CIRCUITS, MULTI-LAYER CIRCUITS, AND METHODS OF MANUFACTURE THEREOF

摘要

An electrical circuit material having a conductive layer disposed a substrate, wherein the substrate comprises an organic or inorganic polymer comprising a covelently bound polyhedral silsesquioxane (POSS). The substrate may further comprise an additional dispersed POSS, any other fillers including fibrous webs. Use of covelently bound POSS allow for flame retardancy in compositions having acceptable dielectric constants and dissipation factors.
