Abstract: The method of surfactant self-assembly to construct supramolecular gel materials is an important way to obtain functional soft matter materials. Driven mainly by the metal coordination of zinc ions, supplemented by other intermolecular non-covalent interactions such as hydrogen bonds and hydrophobic solvents, an anionic glycosylated surfactant self-assembled in a protic ionic liquid of ethylammonium nitrate(EAN)to form a fibrous three-dimensional network structure. The formation mechanism, microscopic morphology and macroscopic properties of ionogels were deeply explored. It was confirmed that the ionogels, as epidermal electrodes, possessed the ability to monitor human electrophysiological signals with high quality, which expanding the application scope of supramolecular gel materials.

Key words: sugar-based surfactant, metal coordination, ionogel, electrophysiological signals
