Graphene oxide films, fibers, and membranes

Abstract

Graphene oxide (GO) macroscopic films, fibers, and membranes have become important applications of this interesting two-dimensional material due to their specific properties and great potential as new high-performance materials. After chemical or thermal reduction, GO is transformed into an electrically conductive material termed reduced GO (RGO). These materials hold great potential because they can be prepared in large quantities at low costs, and consequently they are particularly suitable for applications in packaging, textiles, energy devices, and separation technologies. In the following years, the use of GO- and RGO-based films, fibers, and membranes is expected to grow; however, several challenges regarding its processing conditions must be resolved. In this review, we addressed some of the recent work regarding these important technologies and summarized the state of the art of GO films, fibers, and membranes.
