Supramolecular Hydrogel of Bile Salts Triggered by Single-Walled Carbon Nanotubes

A supramolecular hydrogel of bile salts triggered by single-walled carbon nanotubes (SWCNTs) can be extended 50-fold along the direction of additional stretching force and has excellent viscoelastic properties. The hydrogel is suitable for fabrication of SWCNT-based nanopatterns and devices by a top-down process. The supramolecular hydrogel has the potential for use in rheological materials and in flexible electronics applications.
