“…The results suggest the successful sulfonation of rGO, enhancing solubility, stability, and dispersibility in polar solvents (Figure 3) [42]. GO composite exhibits MgO-water interaction, decreased GO peaks, hydroxyl stretching/bending, and carbonate symmetry [43]. GO and rGO undergo hydroxyl, carboxylic, and carbonyl group elimination with heating, leading to exfoliation in 7 min [44].…”

“…82 Graphene needs to be oxidized to graphene oxide (GO) before functionalization because of the availability of reactive sites on GO. [83][84][85] Through the graft-to or graft-from way, the length of macromolecule chains bonded to GO can be controlled, which is favor to create nanocomposites with desirable properties. Polymers with reactive functional groups including PMMA, PEG, PVA, and polyamide are mainly grafted onto GO.…”

When fabricating polymer nanocomposites (PNCs), it is difficult for nanoparticles to disperse stably in polymer matrix since their high-surface energy can cause them to attract each other. In this paper, we review the effects of nanoparticle size, surface chemical properties, and thermodynamic parameters on the dispersion state of nanoparticles (including inorganic and organic particles) in PNCs and describe some key measures to promote the nanoparticles dispersion. The ideal nanoparticles dispersion in polymer melt is available when the particle size is smaller than the rotation radius of polymer chains and the particle surface is highly compatible or has interactions with the matrix. In polymer solution, establishing proper thermodynamic parameters is necessary to ensure the balance interactions among particles, solvents, and polymers, leading to the successful preparation of PNCs with ideal structure. These results could supply theoretical suggestions for the design of PNCs. Moreover, the equilibrium dispersion may be unavailable without reasonable kinetic parameters, even if the dispersion process is thermodynamically favorable. Therefore, more studies are required on both thermodynamics and kinetics of the dispersion process.

“…Cuprous oxide (Cu 2 O) is one of the most intensively studied metal oxide semiconductor materials and has been applied in many fields, such as photocatalysis, sensors, , nanomotors, and antibacterials . Of course, many other extensive applications of metal oxides have also been reported. − In particular, the advantages of low cost, high efficiency, and easy synthesis make Cu 2 O popular as an organic reaction catalyst. However, nanoparticles, including Cu 2 O nanoparticles, face a common problem: severe agglomeration of nanoparticles, which can adversely affect the reusability of powdered catalysts in industrial organic synthesis.…”

Cuprous oxide (Cu2O) nanoparticles as organic catalysts have been widely applied due to their low cost, high efficiency, and nontoxicity. However, severe agglomeration of nanoparticles would cause side effects on the catalytic performance. Herein, Cu2O micro/nanoparticles were encapsulated into activated carbon felt (ACF) (Cu2O@ACF) to solve nanoparticle agglomeration, and then, three products (alkenylboronates, diaryl sulfides, and 1,2,3-triazoles) were successfully prepared using Cu2O@ACF as the catalyst. In particular, Cu2O@ACF also showed excellent recycling performance for catalytic reactions. After 10 cycles, the yield of alkenylboronates remained high (up to 63%). ACF as a carrier can suppress the aggregation of Cu2O micro/nanoparticles during the process of catalytic reaction, contributing to the improvement of high yield even after ten cycles. This work proposes a simple method to improve the catalytic performance of Cu2O micro/nanoparticles by encapsulating micro/nanoparticles into ACF.
