“…[11][12][13] Bromine has a lower electronegativity than fluorine and bromination of graphite and CNTs usually results in an adsorption of bromine species, 4,14 although covalent bonding between bromine and carbon atoms is also possible. 4,15,16 Ionic bromine doping enhances the conductivity of graphite, graphene, and CNTs 4,[17][18][19][20] improving their electrochemical properties in Li-ion batteries 21 and gas sensor efficiency. 22 Bromine forms layers between the graphite sheets that promotes isolation of monolayers.…”

“…CNTs used in the anode material, instead of traditional materials such as graphite, improve electrochemical performance by increasing the surface area and high electrical conductivity [ 86 ]. It was found that the functionalization of CNT surfaces, e.g., by introducing heteroatoms into the structure of multi-wall carbon nanotubes, improves their conductivity, stability and optimization of work in electrochemical devices, for everyday and specialist use [ 87 , 88 , 89 ]. Additionally, the modification of MWCNT with derivatives of tio- or selenophosphorous acids can form the basis for the construction of new electrochemical cells (as a basic component of electrodes).…”

Nanotechnology is a dynamically developing field of science, due to the unique physical, chemical and biological properties of nanomaterials. Innovative structures using nanotechnology have found application in diverse fields: in agricultural and food industries, where they improve the quality and safety of food; in medical and biological sciences; cosmetology; and many other areas of our lives. In this article, a particular attention is focused on carbon nanomaterials, especially graphene, as well as carbon nanotubes and carbon quantum dots that have been successfully used in biotechnology, biomedicine and broadly defined environmental applications. Some properties of carbon nanomaterials prevent their direct use. One example is the difficulty in synthesizing graphene-based materials resulting from the tendency of graphene to aggregate. This results in a limitation of their use in certain fields. Therefore, in order to achieve a wider use and better availability of nanoparticles, they are introduced into matrices, most often polysaccharides with a high hydrophilicity. Such composites can compete with synthetic polymers. For this purpose, the carbon-based nanoparticles in polysaccharides matrices were characterized. The paper presents the progress of ground-breaking research in the field of designing innovative carbon-based nanomaterials, and applications of nanotechnology in diverse fields that are currently being developed is of high interest and shows great innovative potential.

“…Bromination is another way to modify and purify carbon CNTs using halogenous compounds inferring changes in their electronic structure and chemical reactivity [177]. Bulusheva et al synthetized DWCNTs then functionalized them by bromine vapor at room temperature.…”

Carbon nanotubes (CNTs) have emerged worldwide because of their remarkable properties enlarging their field of applications. Functionalization of CNTs is a convenient strategy to tackle low dispersion and solubilization of CNTs in many solvents or polymers. It can be done by covalent or noncovalent surface functionalization that is briefly discussed regarding the current literature. Endohedral and exohedral are conventional methods based on covalent and van der Waals bonding forces that are created through CNT functionalization by various materials. In this paper, a review of new approaches and mechanisms of functionalization of CNTs is proposed, including amidation, fluorination, bromination, chlorination, hydrogenation, and electrophilic addition. Our analysis is supported by several characterization methods highlighting recent improvements hence extending the range of applicability of CNTs.
