Why Are Polymers Not Good Conductors Of Electricity?

by

Why Are Polymers Not Good Conductors Of Electricity? Polymers are organic macromolecules and therefore having covalent bonds, which are directional bonds. Thus, the electrons are locked in these bonds, cannot being drift along the material, resulting in the poor conductivity. Why are some metals not conductive? but note that some non-metal can conduct electricity like

What Is The Effect Of Temperature On Semiconductor?

by

What Is The Effect Of Temperature On Semiconductor? When the temperature is raised, some of the covalent bonds in the semiconductor break due to the thermal energy supplied. The breaking of bonds sets those electrons free which are engaged in the formation of these bonds. The result is that a few free electrons exist in
