Special Issue Information

Dear Colleagues,

Graphene, which was only discovered within the last century, promises to revolutionize various fields thanks to its strength (despite its thinness); thermal and electrical conductivity; optical and mechanical properties, etc. In particular, when combined with polymeric matrices, graphene prompted the development of advanced nanocomposites with unique and peculiar properties, marking an important turning point in the field of material science. Nanocomposite materials are increasingly adopted for practical applications in fields such as electronics, electrochemical science, energy storage, catalysis, biomedical sensing, and drug delivery. Proper material selection is required to obtain an optimal interfacial interaction, leading, in turn, to the best-performing nanocomposites. However, despite the promising achievements made thus far, several influencing factors render the properties of the resulting materials suboptimal; these include the tendency of graphene to roll up, agglomerate, and form highly oxidized domains. The forthcoming Special Issue, “Graphene-based nanocomposites: latest findings in their design, characterization, and modeling”, aims to highlight the latest academic and industrial advances in this field. Therefore, we welcome new experimental findings and theoretical and simulation studies on graphene-based nanocomposites.

As a renowned scientist in this field, you are invited to submit a short communication, full paper, or review for publication in this Special Issue.

The current state of the art on material science emphasizes recent research efforts aimed at designing novel materials characterized by low-density and advanced properties. The present article reports the experimental, theoretical and simulation results on the thermal behavior of 3D printed discs. Filaments of pure poly (lactic acid) PLA and filled with 6 wt% of graphene nanoplatelets (GNPs) are used as feedstocks. Experiments indicate that the introduction of graphene enhances the thermal properties of the resulting materials since the conductivity passes from the value of 0.167 [W/mK] for unfilled PLA to 0.335 [W/mK] for reinforced PLA, which corresponds to a significantly improvement of 101%. Exploiting the potential of 3D printing, different air cavities have been intentionally designed to develop new lightweight and more cost-effective materials without compromising their thermal performances. Furthermore, some cavities are equal in volume but different in the geometry; it is necessary to investigate how this last characteristic and its possible orientations affect the overall thermal behavior compared to that of an air-free specimen. The influence of air volume is also investigated. Experimental results are supported by theoretical analysis and simulation studies based on the finite element method. The results aim to be a valuable reference resource in the field of design and optimization of lightweight advanced materials. Full article

In this study, β-cyclodextrin-modified reduced graphene oxide aerogels (β-CD-rGOAs) were synthesized via a one-step hydrothermal method and were used to remove hexamethyldisiloxane (L2) from biogas. The β-CD-rGOAs were characterized by the Brunner–Emmet–Teller technique, using Fourier-transform infrared spectroscopy, Raman spectrometry, scanning electron microscopy (SEM), contact angle measurements, and X-ray diffraction. The results of the characterizations indicate that β-CD was grafted onto the surface of rGOAs as a cross-linking modifier. The β-CD-rGOA had a three-dimensional, cross-linked porous structure. The maximum breakthrough adsorption capacity of L2 on β-CD-rGOA at 273 K was 111.8 mg g−1. A low inlet concentration and bed temperature facilitated the adsorption of L2. Moreover, the β-CD-rGOA was regenerated by annealing at 80 °C, which renders this a promising material for removing L2 from biogas. Full article
