“…In a similar way, other researches have been treated CNPs by plasma polymerization using different monomers to coat carbon nanostructures [24,28,29]. Plasma technology also has been used recently to modified graphene materials and novel properties have been found as a result of this plasma treatment such as photoluminescence [30] and semiconductivity [31] and selective detection for biosensors [32,33].…”

Carbon nanofibers (CNFs), graphene platelets (GPs), and their mixtures were treated by plasma polymerization of propylene. The carbon nanoparticles (CNPs) were previously sonicated in order to deagglomerate and increase the surface area. Untreated and plasma treated CNPs were analyzed by dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and thermogravimetric analysis (TGA). DLS analysis showed a significant reduction of average particle size, due to the sonication pretreatment. Plasma polymerized propylene was deposited on the CNPs surface; the total amount of polymerized propylene was from 4.68 to 6.58 wt-%. Raman spectroscopy indicates an increase in the sp 3 hybridization of the treated samples, which suggest that the polymerized propylene is grafted onto the CNPs.

“…Nitrogen forms pyridine (pyridinic-N), pyrrole (pyrrolic-N), and graphite configurations (quaternary, graphitic-N) with carbon atoms in the graphene lattice [36,[44][45][46][47]. Pyridinic-N is bonded to two carbon atoms of the hexagonal graphene cell on the edge of vacancy-type defects and introduces 1 p-electron into the π-system; pyrrolic-N introduces 2 p-electrons into the π-system and is connected to two graphene atoms of the pentagonal cell; graphitic-N replaces the carbon atom in the hexagonal ring of graphene [36,44,47].…”

Plasma treatment of graphene oxide (GO) is of interest for many applications such as gas sensors, flexible electrodes, biological applications, supercapacitors, batteries, etc. Plasma treatment is a high-tech process of processing materials in combination with efficiency, economy and environmental friendliness. At the same time, plasma treatments can lead to an increase in the defectiveness of the surface of GO. Therefore, it is important to know how the treatment in various gas media affects the properties of GO. This is necessary for the correct selection of processing parameters in order to reduce the negative impact of plasma treatment. The review presents the results of experimental studies of the effect of plasma in gases of oxygen, nitrogen, ammonia, sulfur hexafluoride, carbon tetrafluoromethane, hydrogen and methane on the properties of GO. Plasma treatments were used for the functionalization, reduction, doping of graphene oxide, and also for the obtaining GO from graphene by oxidation in oxygen plasma. The effects of plasma treatment are largely determined by the type of ions used and processing conditions: plasma power, processing time and temperature, pressure, as well as the location of the samples in the reaction chamber and their distance from the plasma ignition zone.

“…66a) (Schiros et al 2012;Usachov et al 2014). From this point of view, several experiments using RF-discharge N-containing plasmas have been performed so far, where one remarkable point was to clarify the structures of N-doped graphene and their relation to electronic structures (Wang et al 2010;Lin et al , 2014Jeong et al 2011;Lin et al 2014;Akada et al 2014;Rybin et al 2016). It is now recognized that an important factor common to the results was the plasma treatment (or exposure) time.…”

A similar experimental approach was carried out by observing the shift of valence band maximum of NH 3 -plasma-treated graphene with ultraviolet photoelectron spectroscopy (UPS) (Rybin et al 2016). N-doped graphene holds the promise of applications for fuel cells, lithium-ion batteries, bio-sensors, and ultracapacitors.…”

Since the discovery of fullerenes more than three decades ago, new kinds of nanoscale materials of carbon allotropes called ''nanocarbons'' have so far been discovered or synthesized at successive intervals as cases such as carbon nanotubes, carbon nanohorns, graphene, carbon nanowalls, and a carbon nanobelt, while nanodiamonds were actually discovered before then. Their attractively excellent mechanical, physical, and chemical properties have driven researchers to continuously create one of the hottest frontiers in materials science and technology. While plasma states have often been involved in their discovery, on the other hand, plasma-based approaches to this exciting field originally hold promising and enormous potentials for advancing and expanding industrial/biomedical applications of nanocarbons of great diversity. This article provides an extensive overview on plasma-fabricated nanocarbon materials, where the term ''fabrication'' is defined as synthesis, functionalization, and assembly of devices to cover a wide range of issues associated with the step-by-step plasma processes. Specific attention has been paid to the comparative examination between plasma-based and non-plasma methods for fabricating the nanocarobons with an emphasis on the advantages of plasma processing, such as low-temperature/large-scale fabrication and diversitycarrying structure controllability. The review ends with current challenges and prospects including a ripple effect of the nanocarbon studies on the development of related novel nanomaterials such as transition metal dichalcogenides. It contains not only the latest progress in the field for cutting-edge scientists and engineers, but also the introductory guidance to non-specialists such as lower-class graduate students.& Rikizo Hatakeyama
