제목 Graphene-incorporated Supramolecular Hydrogel
초록 Supramolecular gels, which manipulate noncovalent interactions to self-assemble into a supramolecular network, are held together by multiple weak, but reversible, interactions. Here we describe new surpamolecular hydrogel incorporating reduced graphene oxide (rGO), in which physical gelation is completed by electrostatic interactions between lithium ions and cyclodextrin-based pseudorotaxanes. The gel is able to provide uniform dispersion of rGO, uo to 8 mg/ml, and its storage stability lasts for more than six months. Gelation behavior was addressed by various characterization techniques, including SEM, TEM, XPS, TGA, XRD, and RAMAN spectroscopies. Such hydrogel properties exhibit peculiar mechanical and electrical properties, which find various potential applications.
