“…Other graphene-based nanostructures are carbon nanotubes (CNTs). Single-walled CNTs are formed by graphene sheets that are rolled into a cylindrical arrangement [44][45][46]. If the CNTs are composed by several layers, a structure consisted in concentric cylinders is formed and is commonly called multi-walled CNTs (MWCNTs).…”

This review is focused on the recent developments of nanocomposite materials that combine a thermoplastic matrix with different forms of graphene or graphene oxide nanofillers. In all cases, the manufacturing method of the composite materials has been melt-processing, in particular, twin-screw extrusion, which can then be followed by injection molding. The advantages of this processing route with respect to other alternative methods will be highlighted. The results point to an increasing interest in biodegradable matrices such as polylactic acid (PLA) and graphene oxide or reduced graphene oxide, rather than graphene. The reasons for this will also be discussed.

“…Fullerene is produced by spherically wrapping 2D GR sheets into 0D closed formations [1,30]. CNTs are formed by graphenic layers containing carbon atoms in sp 2 -hybridized state, which are rolled up into a hollow, cylindrical arrangement [31][32][33]. Their important feature is their very high aspect ratio, which is given by their diameter, which is in the range of several nanometers, and length, which can even reach up to millimeters.…”

“…There are two main groups of functionalization methods, namely, covalent and non-covalent functionalization. The first group of functionalization methods is characterized by the surface oxidation of carbon and the binding of organic/inorganic ions/atoms/molecules via covalent bonds, using atoms (fluorine or nitrogen), functional groups (hydroxyl, amino or carboxyl groups), biomolecules, or polymers, at end-caps and defect sites [32,51]. Consequently, the interfacial interactions of GR are highly enhanced.…”

Graphene-based nanomaterials have been intensively studied for their properties, modifications, and application potential. Biomedical applications are one of the main directions of research in this field. This review summarizes the research results which were obtained in the last two years (2017-2019), especially those related to drug/gene/protein delivery systems and materials with antimicrobial properties. Due to the large number of studies in the area of carbon nanomaterials, attention here is focused only on 2D structures, i.e. graphene, graphene oxide, and reduced graphene oxide.

“…Conductive polymer composites (CPCs) have attracted extensive scientic attention due to their high electrical conductivity and good mechanical properties. [1][2][3][4][28][29][30][31][32][33][34][35] They are utilized in many applications, such as sensors, fuel cell electrodes, and batteries. [5][6][7] The CPCs are usually obtained by mixing a polymer matrix with conductive llers, such as carbon bers (CFs) or carbon nanotubes (CNTs) or carbon black (CB), etc.…”
