Outline of Final Research Achievements |
In order to develop a temperature-responsive phase transition draw solute that has high osmotic pressure and significantly reduces membrane leakage due to its three-dimensional molecular structure, a new bulky Gemini-type ionic liquids with a lower critical solution temperature were synthesized. As a result, it was shown that some Gemini-type ionic liquids obtained by controlling the hydrophobicity of cations and anions can reduce the leakage of DS while maintaining the water permeation flux.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,駆動溶質(DS)の構造を嵩高くし、その構造をイオン液体化することにより、漏洩性を低く保ち、その構造の一部をイオン液体化することにより高浸透圧の発現を高浸透圧と超低膜漏洩性の両性質を兼ね備えたDS分子を新たに創製を試みた。このようなDSの検討例はこれまでになく,学術的に大きな意義がある。これらの成果によってFO膜プロセスという膜工学領域の開拓を促進し、分離工学に革新をもたらすことが期待される。
