The article contains the following contents:
Mol. dynamics simulations were applied to explore the ion transport in five ionic liquid/poly(vinylidene fluoride) (IL/PVDF) systems under different elec. fields where the cation is 1-ethyl-3-methylimidazolium (EMI+) and the anions are Cl–, Br–, BF4–, PF6– and trifluoromethanesulfonate (TfO–) sep., and each system contains about 40 wt% of IL. The structural properties were analyzed by the following calculations as elec. fields increase. The pair correlation function reveals that the local spatial structure of ion pairs can be split into two types, which tend to disorder; the dihedral angle and mean square radius of gyration show that PVDF chains tend to straighten. The ion transport properties were studied by the ion-pair intermittent time correlation function and continuous time correlation function, the diffusion coefficient and mobility of anions and cations as elec. fields increase. The simulation results illustrate that ion transport is intensified. In addition, the relationship between diffusion coefficient and the elec. fields can be fitted into an exponential function, and the fitting parameters are strongly related to the local structure of the ion pairs, and the relationship between ideal conductivity and the elec. fields has the same law. Specially, the anions mobility is determined by the anions volume under the stronger elec. fields, and the smaller the anion volume, the greater the mobility.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a starting material for the preparation of 1-ethyl-3-methylimidazolium chloride/tetrafluoroborate (EMI.Cl.BF4) molten salt for electrochemical studies; a solvent as well as catalyst for the depolymerization of oak wood lignin.HPLC of Formula: 65039-09-0
