Special Issue Information

Dear Colleagues,

Since the discovery in 2004 of the groundbreaking properties of graphene, a truly one-atom-thick two‑dimensional crystal of conjugated carbons arranged in a honeycomb lattice, there has been intense and growing research interest due to the potential of its utilization in high technological-impact applications. Due to its remarkable electrical and thermal conductivity, transparency to light, and mechanical flexibility and strength, graphene-related materials (GRms) have evolved as attractive and efficient candidates for a wide range of advanced applications, from spintronics, electronics, and sensing, to energy storage, metal-free (electro)catalysis, and environmental remediation. The potential to undergo a plethora of controllable chemical modifications/functionalizations, such as oxidation or fluorination towards graphene oxide or fluorographene, or doping with diverse atoms and other phases, can lead to desirable tweaking of the physical, chemical, magnetic, and/or optoelectronic features, tailored for the targeted application. Furthermore, the use of graphene-based materials is considered as a green-oriented approach, and various GRms have already appeared in the market. Going a step ahead, GRms can be utilized as fillers/additives or as substrates for various substances, ranging from quantum dots to biomolecules, towards the synthesis of composites or hybrids. This approach can lead to unique synergistic properties of the derived new materials.

The main aim of this Special Issue “Graphene-Related Materials: Synthesis and Applications” is to collect selected original and innovative articles presenting the very recent trends and advances on the design, synthesis, modifications, characterization, and applications of graphene-based materials and their composites. The field of the applications of these materials is not limited, although the foremost interest is within the areas of energy storage and conversion, electronics, medicine, adsorption, catalysis, sensing, and structural composites. Environmentally friendly and sustainable applications are also of a great interest. We welcome submissions of original research papers, communications, or reviews.

New Limits for Stability of Supercapacitor Electrode Material Based on Graphene Derivative
Nanomaterials 2020, 10(9), 1731; https://doi.org/10.3390/nano10091731 - 31 Aug 2020

Supercapacitors offer a promising alternative to batteries, especially due to their excellent power density and fast charging rate capability. However, the cycling stability and material synthesis reproducibility need to be significantly improved to enhance the reliability and durability of supercapacitors in practical applications. Graphene acid (GA) is a conductive graphene derivative dispersible in water that can be prepared on a large scale from fluorographene. Here, we report a synthesis protocol with high reproducibility for preparing GA. The charging/discharging rate stability and cycling stability of GA were tested in a two-electrode cell with a sulfuric acid electrolyte. The rate stability test revealed that GA could be repeatedly measured at current densities ranging from 1 to 20 A g−1 without any capacitance loss. The cycling stability experiment showed that even after 60,000 cycles, the material kept 95.3% of its specific capacitance at a high current density of 3 A g−1. The findings suggested that covalent graphene derivatives are lightweight electrode materials suitable for developing supercapacitors with extremely high durability. Full article

Herein, we present an interesting route to carbon derived from ferrocene without pyrolysis. Specifically, the direct contact of the metallocene with liquid bromine at ambient conditions released rapidly and spontaneously carbon soot, the latter containing dense spheres, nanosheets, and hollow spheres. The derived carbon carried surface C-Br bonds that permitted postfunctionalization of the solid through nucleophilic substitution. For instance, treatment with diglycolamine led to covalent attachment of the amine onto the carbon surface, thus conferring aqueous dispersability to t he solid. The dispersed solid exhibited visible photoluminescence under UV irradiation as a result of surface passivation by the amine. Hence, the present method not only allowed a rapid and spontaneous carbon formation at ambient conditions, but also surface engineering of the particles to impart new properties (e.g., photoluminescence).

The preparation of hybrid polymeric systems based on carbon derivatives with a cationic polymer is described. The polymer used is a copolymer of a quaternizable methacrylic monomer with another dopamine-based monomer capable of anchoring to carbon compounds. Graphene oxide and graphene as well as hybrid polymeric systems were widely characterized by infrared, Raman and photoemission X-ray spectroscopies, electron scanning microscopy, zeta potential and thermal degradation. These allowed confirming the attachment of copolymer onto carbonaceous materials. Besides, the antimicrobial activity of hybrid polymeric systems was tested against Gram positive Staphylococcus aureus and Staphylococcus epidermidis and Gram negative Escherichia coli and Pseudomonas aeruginosa bacteria. The results showed the antibacterial character of these hybrid systems. Full article

The excellent electrical properties of graphene provide a new functional finishing idea for fabricating conductive cotton fabrics with antistatic properties. This work develops a novel method for synthesizing active graphene to make cotton fabrics conductive and to have antistatic properties. The graphite was oxidized to graphene oxide (GO) by the Hummers method, and was further acid chlorinated and reacted with the para-ester to form the active graphene (JZGO). JZGO was then applied to cotton fabrics and was bonded to the fiber surface under alkaline conditions. Characterizations were done using FT-IR, XRD and Raman spectroscopy, which indicated that the para-ester group was successfully introduced onto JZGO, which also effectively improved the water dispersibility and reactivity of the JZGO. Furthermore, this study found that the antistatic properties of the fabric were increased by more than 50% when JZGO was 3% by weight under low-humidity conditions. The washing durability of the fabrics was also evaluated. Full article
