Our experimental observations are consistent with the recently reported solvation structure of PEO in these solutions (Stefanovic et al., 2018). The increased charge density from NO₃⁻ to Br⁻ to Cl⁻ results in greater net ionic interaction between the ionic charge centres. As PEO interacts with PAN primarily through the ammonium hydrogens of the cation, this increased ionic interaction effectively displaces the PEO, resulting in poorer solvation.]]> Wed 24 May 2023 15:03:35 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34338 Wed 24 Jul 2019 13:04:50 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35397 - and Br^- anions to PAN disrupts the structure within the PAN charged domain due to competition between nitrate and halide anions for the ammonium charge centre. This disruption increases with halide concentration (up to 10 mol. %). However, at these concentrations, halide addition has little effect on the structure of the PAN nonpolar domain. Addition of PEO to pure PAN also disrupts the structure within the charged domain of the liquid due to hydrogen bonding between the charge groups and the terminal PEO hydroxyl groups. There is little other association between the PEO structure and the surrounding ionic liquid solvent, with strong PEO self-interaction yielding a compact, coiled polymer morphology. Halide addition results in greater association between the ionic liquid charge centres and the ethylene oxide components of the PEO structure, resulting in reduced conformational flexibility, compared to that observed in pure PAN. Similarly, PEO self-interactions increase in the presence of Cl^- and Br^- anions, compared to PAN, indicating that the addition of halide salts to PAN decreases its utility as a molecular solvent for polymers such as PEO.]]> Wed 24 Jul 2019 12:34:21 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26887 Wed 11 Apr 2018 11:23:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:14679 Wed 11 Apr 2018 10:12:06 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27923 Sat 24 Mar 2018 07:36:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35888 Mon 13 Jan 2020 17:15:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19863 Mon 12 Aug 2019 14:17:31 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34404 Mon 03 Apr 2023 16:07:20 AEST ]]>
