Supramolecular Gels with Mouldable Properties from Fatty Acid to make Graphene-Based Nanohybrid Paper

Abstract

''Paper-like'' materials composed of graphene exhibit good mechanical, thermal and electronic properties and are expected to find a variety of applications. Herein, a simple and elegant strategy has been reported to obtain a graphene-based nanohybrid paper. Mysristic acid in sodium salt-containing aqueous solution forms a stable hydrogel. When myristic acid was mixed with glucose and graphene oxide produces graphene-based gel under the treatment of heating and subsequent cooling through electrostatic stabilization. By applying proper mechanical compression on gel a stable and flexible nanofibrillar graphene-based paper has been obtained without destroying the network structure. This study has enabled to develop of a facile approach to large-scale production of graphene-based paper. The properties of this graphene-based paper have been investigated using electron microscopy, FT-IR spectroscopy, X-ray diffraction and Raman spectroscopy. The obtained paper is thermally stable and resistant to a wide range of organic solvents and therefore interesting in making various advanced electronics.
