Аннотация
Peculiarities of the formation of a reticular polymeric gel—electrolyte matrix based on polyethylene glycol diacrylate in a medium of ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF4) were studied by isothermal calorimetry. The influence of the polymeric matrix structure on the ionic and molecular mobility of a LiBF4 salt—ionic liquid electrolyte system was considered. The self-diffusion coefficients on the 1H, 7Li, and 19F nuclei were measured by pulsed field gradient NMR. For the all electrolyte compositions, the highest translation mobility of the cationic part of the EMI+ ionic liquid molecule is observed on 1H nuclei, whereas the lowest one corresponds to 7Li nuclei. This phenomena is due to the strong association of the lithium salt in a polar medium of the ionic liquid, which is concentrated in cavities of the reticular polymer.
