제목 Morphological transformation of perfluorinated sulfonic acid ionomer via ionic complex formation in a relatively high entropy state
초록 Perfluorinated sulfonic acid (PFSA) ionomers with high ionic conductivity and excellent chemical durability have been perceived as energy materials used in a wide range of applications such as polymer electrolyte membrane fuel cells, redox-flow batteries, and water purification. PFSA ionomers, however, have a critical limitation in tuning their fundamental characteristics owing to their fixed chemical integrities including architecture, and equivalent weight. PFSA ionomers have relatively well-defined morphologies derived from hydrophilic-hydrophobic microphase separation, which contributes to water channel formation for fast ion transport. In this study, a simple approach to induce more advanced morphologies is proposed. This approach is also expected to fairly shorten the membrane formation time.
