摘要
Use of liquid crystalline polymers together with polyhedral oligomeric silsesquioxane (POSS) fillers either in place of or together with conventional fillers yields improved dielectric materials for circuits. POSS-filled systems typically exhibit lower mass densities and greater stiffness, and are capable of withstanding higher temperatures, as well as higher levels of ionizing radiation. In addition, POSS-filled polymers are capable of wetting fibers and fillers to desirably high degrees. They may also help to minimize polymerization shrinkage, lower viscosity and increase material toughness.
