Various synthetics (fluoro-polymers, polypropylene, polypropylene-terephthalate) exhibit molecules which are "directional" in a strong electrostatic field.
For all 'electret' materials goes that the ohmic resistance should be low and remain so after the 'polarization' has taken place.
The best materials to date are: (organic): Teflon; this appears to stay directed stable for many years. (Inorganic molecules): Quartz (SiO2), (MnO2), TiO2) also show "electret" properties.
The negative charge section in these molecules is located at the O atoms. It should be noted: Atoms, in the transitional area, such as Cr, Mn and to a lesser extent Si and Ti are not strong positive or
even negative, but with respect to the two O atoms in their oxides, which are strongly negative, is there indeed bipolarity.
For the organic "waxes" and with cellulose their di-polarity shows from the fact that concentrations of O atoms, respectively, of OH groups, at one end of these longer molecules exist.
