摘要: We incorporated polymer-grafted nanoparticles into ionic and zwitterionic liquids to explore the solvation confinement effects on their heterogeneous dynamics using quasi-elastic neutron scattering (QENS). 1-Hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (HMIM-TFSI) mixed with deuterated poly(methyl methacrylate) (d-PMMA)-grafted is studied unravel how dynamic coupling between PMMA HMIM-TFSI influence fast slow diffusion characteristics of HMIM+ cations. The liquid, 1-butyl-3-methyl imidazole-2-ylidene borane (BMIM-BH3) critically selected PMMA-grafted for comparison in this work as its ions do not self-dissociate it does couple through ion-dipole interactions does. find that long-range unrestricted cations higher well-dispersed particles than aggregated particle systems, whereas localized measured be close-packed particles. Translational BMIM-BH3 influenced by any structures suggesting zwitterions interact PMMA. This difference two liquid types enables us decouple polymer from liquids, which integral understand transport mechanism confined nanoparticle electrolytes.
