Special Issue Information
Dear Colleagues,
In recent years, graphene oxide (GO) and reduced graphene oxide (r-GO) have received a great deal of attention as precursors of graphene-like 2D layered nanomaterials. These materials have unique intrinsic physical and chemical properties, in addition to having a large surface area, functionality containing oxygen, good conductivity, and good biocompatibility. For this reason, many experimental studies have been conducted to improve GO and r-GO, and to analyze their possible application fields. Recently, there has been a growing number of intensive studies which address the preparation and characterization of new nanocomposites which integrate GO or r-GO (GO/r-GO) with polymers, inorganic nanoparticles (metal, metal oxide, etc.), or even nanotubes and fullerenes. These nanocomposite materials with novel nanostructures and integrated properties are receiving an increasing interest.
For example, GO/r-GO-based polymer nanocomposites are receiving remarkable interest due to their excellent mechanical, thermal, and electrical properties. GO/r-GO used as nanometric filler embedded in a polymeric matrix enhance the structural, morphological, and functional properties of the composite material. In addition, these materials are suitable for electronic and energy storage applications in the form of polymer–graphene composites.
Nanocomposites based on GO/r-GO and inorganic nanoparticles such as Au, Ag, Pt, etc. have attracted great attention for various applications as catalysts, photocatalysts, electrodes, sensors, substrates for surface-enhanced Raman spectroscopy, and biomedical applications. So, the development of new synthesis methods for GO/r-GO and nanoparticle composites with good control of size and morphology is necessary to obtain interesting devices.
In addition, the combination of GO/r-GO with different dimensions of carbon-based materials has shown superior performance in several cases; for example, a GO/r-GO and fullerenes system produced membranes with excellent structural stability.
In conclusion, the aim of this Special Issue is to extend our current knowledge about “Advanced Nanocomposite materials Based on Graphene Oxide/Reduced Graphene Oxide”, and it is our honor and pleasure to invite you to submit a manuscript. Original research papers, state-of-the-art reviews, communications, and discussions are welcomed.

Abstract: Graphene oxide (GO) has recently arising a fascinating interest in a broad range of biomedical applications, being employed as efficient antimicrobial and angiogenic agent, mostly related to the intracellular formation of reactive oxygen species. In addition, owing to its large surface area, based on a carbon skeleton with many hydrophilic functional groups (i.e., hydroxyl, carboxyl, epoxy bridge, and carbonyl moieties), GO may provide a convenient access to its readily dispersion within polymeric matrixes, i.e. cellulose, resulting in new synergic properties due to both single components. GO integration in cellulose matrixes opens up to design of highly advanced multifunctional hybrid nanocomposites with tailored properties. In this context, the valorisation of wastes may constitute an interesting platform in the circular bio-economy for the development of high added-value compounds, such GO and cellulose, with remarkable financial and environmental advantages. By giving special attention to recent applications of GO/cellulose nanocomposites, the current review aims at discussing a relationship between structural and physico-chemical properties (i.e., size, edge density, surface chemistry, hydrophilicity) of cellulose/GO nanocomposites with antimicrobials and angiogenic mechanisms that can be advantageously involved in tissue regeneration. Accordingly, after giving an overview of the production processes employed to obtain GO and cellulose-derivatives from waste, the mechanisms, which up regulate antimicrobial and angiogenic pathways of tissue repairing together with the most recent and remarkable findings on GO/cellulose scaffolds will be presented.
