Theoretical Calculation of the Resistivity of Teflon under Shock Loading

The resistivity of Teflon under shock loading is calculated theoretically by means of the Mott and Jones' formula with the addition of its equation of state. The results are compared with the published experimental data. Although they may be in good accord, some mechanisms about the decrease of polymerization number of the Teflon with the increase of shock pressure are still unknown, so the theory is partly phenomenological.
