“…For CF-COOH, compared with the untreated CF, the O-H stretching vibration peak at 3100–3600 cm −1 was enhanced, which proved that the number of active carboxyl functional groups on the fiber surface was increased by acid oxidation treatment. Meanwhile, in spectrum of CF-COOH, the stretching vibration peak corresponding to C = O at 1635 cm −1 is significantly enhanced, 31 which further indicated the opinion above. By observing the images of CF-COOH-MnO 2 and CF-MnO 2 -MA, it can be obviously seen that the stretching vibration peak of the Mn-O bond appears at 440–520 cm −1 , thus attesting the existence of MnO 2 .…”

“…On the one hand, the polar hydroxyl groups on the fiber surface increased obviously due to the growth of MnO 2 nanosheets; while another explanation is that polar amino functional groups of dendritic melamine molecules are introduced on MnO 2 nanosheets. 31,38,39 In summary, the successful preparation of the CF-MnO 2 -MA hierarchical reinforcement structure results in enhancing fiber surface energy, thereby laying a strong foundation for improving the interfacial properties between fiber/resin.…”

“…MA has been widely used in fiber modification, because the amino groups in MA usually form chemical crosslinking with resin, which improve the compatibility between fiber/resin. Zhao M et al 31 grafted MA onto the surface of carbon fiber as a coupling agent, which not only enhanced the polarity of the fiber surface, but also provided more reactive sites for the reaction with the resin matrix, so it effectively improved the interfacial bonding strength of the fiber/resin. If MA can be grafted onto the fiber surface together with MnO 2 nanosheets by chemical bonding and participate in the curing reaction to form a chemical crosslinking with phenolic resin, 32,33 the interface performance of the composite will be greatly improved.…”

To intensify the interfacial properties between carbon fiber (CF) and resin without sacrificing fiber, a new type of carbon fiber reinforced resin composite was designed and fabricated with MnO2 nanosheets and melamine (MA) as interphase. The MnO2 nanosheets were uniformly grown on the carbon fiber via hydrothermal method. And then MA was grafted on the MnO2 nanosheets to from chemical bond with resin by a simple bath shock method. The experiment results show that the flexural and tensile strength of the composite reinforced by CF-MnO2-MA increased by 24.1% and 14.5% compared to that of CF, respectively. And the wear rate is reduced by about 29.6%. In summary, the improvement of mechanical and frictional properties of the composite is related to the synergetic reinforcement in mechanical interlocking and chemical bonding of MnO2 nanosheets and MA.

“…Several works of literature evidenced that GNPs could enhance interlaminar shear strength properties of epoxy composites. 183,184 Cha et al 184 studied the reinforcing mechanism of functionalized GNPs and CNTs in fiberreinforced polymer (FRP) composite. The result showed that f-GNPs and f-CNTs improved the resistance to crack propagation both at the interfaces and within the matrix of the FRPs, which improved the mechanical strength by 219% in the f-GNPs and 61% in the f-CNTs case.…”

Graphene nanoplatelets (GNPs) have received immense attention from the global scientific research community in the 21st century due to their two-dimensional planar structure, high surface area, functionalization abilities, and notable thermal-mechanical-electrical properties. When appropriately integrated into polymer matrices, graphene nanosheets improve the mechanical performance of polymer under static and high-strain rate loading. On the other hand, surface modification of GNPs through functionalization enhances dispersibility and interfacial strength of GNPs/polymer composites. Computational methods for GNPs-based nanocomposites considering micromechanical and multiscale modeling were also developed to predict their thermo-mechanical and electrical properties. These nanocomposite materials have been identified as having a wide range of applications in aerospace, automotive, construction, biomedical, energy storage, sensor, and textiles. In this review paper, recent advances of GNPs/epoxy nanocomposites, including their functionalization processes, characterization techniques, production methods, properties, and potential applications, have been comprehensively explained. Furthermore, it attempts to provide a complete framework for researchers by summarizing and evaluating the extensive literature on these nanocomposite materials.

“…The synthesis protocol of CMF-CNC was reported elsewhere. [51] A comparative adsorption/desorption study of EAIERs and CMF-CNC electrodes was carried out using an NaCl solution with ionic conductivity of 610 μS. It is evident from Figure 4A that the EAIERs electrodes have higher adsorption capacity (≈15.86 mg g −1 ) than CMF-CNC electrodes (≈7.45 mg g −1 ) for Cl − ions.…”

terms of equipment and energy consumption. [6,8-11] Capacitive deionization (CDI) is an emerging technology which involves adsorption and desorption of ions on the electrode surface by application of low potential difference (≈1.2-1.8 V) across a pair of porous carbon electrodes, thereby making it both energy and cost-efficient compared to other existing desalination methods. When a flowing water stream is passed across a CDI system, cations and anions move toward oppositely charged electrodes and get adsorbed on them, thereby generating deionized and 'drinkable' water, starting from brackish water. Subsequently, adsorbed ions can be removed from the electrode by reversing the polarity, thereby regenerating the electrode surface, ready for reuse for next adsorption cycle. [5] Thus, clean water can be produced continuously by repeating the adsorption and desorption cycles. CDI is a cost-effective, point-of-use method with a high theoretical desalination efficiency. [5] However, its practical applications for desalination are yet to be recognized at a large scale, and research is being carried out to synthesize new materials with improved adsorption capacities. [5,12-14] Related technologies such as Faradaic deionization and the use of different 2D materials in CDI are also explored intensely. [15-17] Various carbonaceous materials and their composites are being used as CDI electrodes because of their high salt adsorption capacities in the range of several mg g −1. [18-25] Graphene, and graphene-derivatized materials, such as, graphene-like nanoflakes, [26] activated carbon, [27] activated carbon nanofiber (ACF), [28] reduced graphene oxide (rGO), [27,29] carbon nanotubes (CNT), [29] graphene-CNT composites, [29,30] rGO-ACF, [28] 3D macroporous graphene architectures, [31] sponge-templated graphene, [14] graphene-Fe 3 O 4 , [32] graphene chitosan-Mn 3 O 4 , [33] rGO-activated carbon composites, [27] and functionalized graphene nanocomposite, [34] have been used as CDI electrodes. The adsorption capacities of graphenic composites, such as graphene/carbon nanotube, CO 2 activated rGO, sulfonic functional graphite nanosheets, SO 3 H/NH 2 graphene/activated carbon, MgAl-Ox/G nanohybrids, 3D-graphene architecture, and graphene sponge measured were 1
