| Popis: | Electret properties and structural peculiarities have been studied for fine-dispersed heterogeneous systems using the example of mechanoactivated natural-coal grains immersed into a polar aqueous matrix. The observed accumulation of currents with no external voltage applied indicates the formation of a potential difference of an internal electric field in test objects. It has been shown that an aqueous-phase layer with rigid fixation of water molecules is formed at the interfaces. The layer is capable of acquiring functions of a potential barrier that hampers transitions of both free water molecules and water molecules oriented by the system’s internal electric field. |
