Qu, Minghe;Li, Shenshen;Chen, Jian;Xiao, Yunqin;Xiao, Jijun published 《Molecular dynamics simulations of ionic liquid/poly(vinylidene fluoride) systems: Ion transport with different anions》 in 2022. The article was appeared in 《Solid State Ionics》. They have made some progress in their research.Electric Literature of C6H11ClN2 The article mentions the following:
Mol. dynamics (MD) simulations were applied to explore the ion transport in six ionic liquid/poly(vinylidene fluoride) (IL/PVDF) systems where the cation is 1-ethyl-3-methylimidazolium ([EMIM]) and the anions are [Cl], [Br] [BF4], [PF6], trifluoromethanesulfonate ([TfO]) and bis(trifluoromethanesulfonyl)imide ([NTf2]) sep., and each system contains about 40 wt% IL. The glass transition temperature (Tg = 204 K) of [EMIM][NTf2]/PVDF system is good agreement with the exptl. value (200 K). Transference number of ions, ideal conductivity and viscosity can be calculated based on diffusion coefficient The power law shows mobilities of anions and cations are seen to exhibit a “superionic” behavior when considering all the anions (cations) together. Overall, for the same IL/PVDF system, with the increase of temperature, both the ion-pair relaxation times and lifetimes decrease, while diffusion coefficients of ions increase, so ion motion is intensified. The transference numbers of anions and cations show upward and downward trends resp., indicating that the diffusion coefficients of cations decrease faster than that of the anions. The conductivity gradually increases, and the viscosity gradually decreases. For different IL/PVDF systems, the chem. properties of ion pairs are the main factors affecting ion-pair relaxation times and lifetimes, diffusion coefficients, the conductivity and viscosity at lower temperatures However, the influence gradually weakens as the temperature increases, and the IL/PVDF systems with a large Tg will have smaller the diffusion coefficients, conductivity, as well as higher viscosity at higher temperatures1-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.Electric Literature of C6H11ClN2
