Recently, ionic liquids (ILs) have been introduced into block copolymer (BCP) architectures, which provides a wide range of morphologies in nanometer scale with the self-assembly, to combine the specific properties of ionic liquids such as negligible vapor pressure, high ion conductivity and chemical stability. Here, we studied phase behaviors of PS-b-P2VP and PS-b-PMMA/ionic liquid mixtures. We selected two different ionic liquids, [EMIM][TFIS] and [HMIM][TFSI] to investigate chain length effect on the phase behaviors of PS-b-P2VP and PS-b-PMMA. Distribution of ionic liquids in two different was probed with small angle neutron scattering by contrast variation technique. Nanostructures of each mixtures and thermal stability of the structures were measured by small angle X-ray scattering with varying volume fraction of ionic liquids in the mixtures. |
