Evidence of a net surface charge on lunar regolith components and of their persistent internal polarization was discussed in a recent paper with references to charge significance for particle aggregation (Figs. 1-5); regolith dynamics; lunar dust storms; track density evaluation and albedo. The electret character observed appears to correlate with the irradiation and thermal history of the regolith. Electron microscopy provides direct evidence of microstructural features that promote internal polarization and preservation of charge.The lunar dielectrics do not contain molecular dipoles. Elongated grains in the fines fraction tend to align in the direction of the field at sites of sufficient mobility (Figs. 3, 4, 5), suggestive of electric moments similar to those of polymeric materials whose molecular dipoles aggregate to form supramolecular dipoles. The number density and the distribution of free charge carriers obtained from the various ion implantations in the surface and subsurface layers (depending on particle energies) are heterogeneous and subject to charge redistribution in an applied field.
