Conduction behaviour of Epoxy-carbon Composites and various electrical properties

The conductivity of any material is related to its atomic or molecular structure. The electrons of an atom exist in different energy states corresponding to different orbits around the nucleus. Quantum mechanical considerations permit only a certain number of electrons in a given radial orbit. The electrons in a given circle include a shell. On the off chance that a circle is filled, extra electrons can't enter that shell nor have a vitality related with that dimension. The furthest shell contains the valence electrons, whose circles are generally not filled and are in charge of compound holding. As two iotas attach to one another, their interpenetrating electrons may part into valence groups and conduction groups. These groups are isolated by a hole or vitality distinction. The extent of the vitality hole decides the conductivity of the material. In profoundly conductive materials (e.g., metals), the valence band isn't filled and covers the conduction band. In this way, there are various vitality levels into which an electron can be energized.
