摘要：

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 tet-rafluoroborate (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 H-1, Li-7, and F-19 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 Li-7 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.
