“…Microwaves are effectively absorbed by π-electrons that cause very rapid warming of GO (several hundreds of degrees in few seconds) that results in the breaking of weakest bonds [ 127 ]. According to this principle, r-GO domains with sp 2 carbon network and free π-electrons heat faster than GO-ones that minimize the efficiency of this method [ 128 , 129 ]. When chemically reduced or simultaneously exfoliated and reduced, the quality of r-GO is low and oxygen content is as high as in the case of the conventional thermal method [ 54 , 127 ].…”

The past decade has seen enormous efforts in the investigation and development of reduced graphene oxide (GO) and its applications. Reduced graphene oxide (rGO) derived from GO is known to have relatively inferior electronic characteristics when compared to pristine graphene. Yet, it has its significance attributed to high-yield production from inexpensive graphite, ease of fabrication with solution processing, and thus a high potential for large-scale applications and commercialization. Amongst several available approaches for GO reduction, the mature use of plasma technologies is noteworthy. Plasma technologies credited with unique merits are well established in the field of nanotechnology and find applications across several fields. The use of plasma techniques for GO development could speed up the pathway to commercialization. In this report, we review the state-of-the-art status of plasma techniques used for the reduction of GO-films. The strength of various techniques is highlighted with a summary of the main findings in the literature. An analysis is included through the prism of chemistry and plasma physics.

“…The two sub-peaks are located at 532.6 eV and 533.6 eV, corresponding to the C-O and C-O-C/C-OH groups. 32,33 The peak intensities of the C-O-C/C-OH group and C-O group in LIG samples are basically equal, which is due to the relatively higher carbon content in LIG. Correspondingly, the C-O group peak in the N-LIG sample is slightly stronger than the C-O-C/C-OH group peak, which also confirms that the carbon content in N-LIG is slightly lower.…”

“…In Figure 4A, the peaks of C1s (286.2 eV) and O1s (534.2 eV) are observed in the XPS spectra of acid T300, T300-GO and T300-GO-ATP. [28,29] In addition, N1s (~399.8 eV) peaks are found in T300-GO and T300-GO-ATP, indicating that an amidation reaction took place between T300 and GO or between GO and ATP ( Figure 3A). [30] A Si2P peak was found at 104.3 eV, which verifies that the Si-OH of ATP reacted with the oxygen functional groups on T300-GO to generate T300-GO-ATP, ensuring superior thermal stability even at −196 C. In Figure 4B, compared with the C1s spectrum of Acid T300, T300-GO has C N and O C N peak at 284.9 and 287.3 eV.…”

A mismatch between the expansion coefficients of carbon fiber (CF, T300) and resin causes thermal deterioration at the interface of composite cryotanks. This study presents an effective method to enhance the cryogenic interfacial properties of a T300/epoxy (EP) composite, in which graphene oxide (GO)/attapulgite (ATP) hierarchical structures are chemically grafted onto the surface of T300. GO and ATP were sequentially assembled on the T300 surface, which changed the morphology of T300 and optimized the interfacial wettability of T300/EP. Surface topography and chemical bonding of grafted T300 fibers (T300-GO-ATP) were evaluated by SEM and XPS, respectively. Considering the functioning conditions of composite cryotanks, three cryogenic interfacial testing conditions were designed for the T300-GO-ATP/EP composites: −196 C, cryogenic cycling (from RT to −196 C), and immersion in liquid nitrogen (LN 2). The interfacial shear strength (IFSS) of T300-GO-ATP/EP composite at −196 C was 88.3 MPa, 53.1% stronger than that of T300/EP (57.6 MPa). Likewise, the IFSS of T300-GO-ATP/EP composites was tested under cryogenic cycling/immersion in LN 2 , which increased remarkably comparing to those of T300/EP under the same conditions. Results shows that GO/ATP suppress interfacial cracking and enhances the interfacial bonding of T300/EP at cryogenic temperatures through chemical bonding and nanointerlocking.
