EO solubility mainly depends on the hydrogen bond network density, and decreases in the order H₂O, EAN, and then PAN. The solubility of the EGE and GPrE blocks decreases in the order PAN, EAN then water because the large apolar domain of PAN increase the solubility of the solvophobic blocks more effectively than the smaller apolar domains in EAN, and water, which is entirely hydrophilic; GPrE is less soluble than EGE because its larger size hinders solubilization in the IL apolar domains. Large disk-shaped structures were present for EGE₁₀₉EO₅₄ in all three solvents because short EO chains favor flat structures, while GPrE₉₈EO₂₆₀ formed spherical structures because long EO chains lead to curved aggregates. The aggregate structures of EGE₁₁₃EO₁₁₅ and EGE₁₀₄EO₁₇₈, which have intermediate EO chain lengths, varied depending on the solvent and the temperature. Solubilities also explain trends in critical micelle concentrations (cmc) and temperatures (cmt).]]> Wed 11 Apr 2018 12:26:49 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27922 [Li(G4)]ClO₄ > [Li(G3)]TFSI due to decreased availability of Li⁺ for PEO coordination. For the same glyme length, the solvent qualities of SILs with TFSI⁻ and BETI⁻ anions ([Li(G4)]TFSI and [Li(G4)]BETI) are very similar because they weakly coordinate with Li⁺, which facilitates Li⁺–PEO interactions. [Li(G4)]ClO₄ presents a poorer solvent environment for PEO than [Li(G4)]BETI because ClO₄⁻ binds more strongly to Li⁺ and thereby hinders interactions with PEO. [Li(G3)]TFSI is the poorest PEO solvent of these SILs because G3 binds more strongly to Li⁺ than G4. Rheological and radius of gyration (R_g) data as a function of PEO concentration show that the PEO overlap concentrations, c* and c**, are similar in the three SILs.]]> Sat 24 Mar 2018 07:36:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4435 Sat 24 Mar 2018 07:22:47 AEDT ]]>
