Which material has the best combination of low dielectric constant and high compressive strength?
Tricky one this. However, I’ll do my best here. As you know, a dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements are necessary. The “dielectric constant is a ratio” of the capacitance of a capacitor in which a “particular insulating material” is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric. Most materials used for capacitors have substantially higher dielectric constant than polymers. Most of these high-permitting dielectrics are “Ceramics” such as barium titan-ate and these can be used as fillers in polymers to increase the dielectric constant if this is required, thus – controlled at a low or high compressive strength, to answer your questi
