“…Pure SWCNTs, as well as MWCNTs coatings, have been obtained [31][32][33], but the composite or hybrid layers are even more extensively developed as, e.g., CNTs-HAp [13,22,23,[34][35][36][37] or CNTs-graphene oxide [38]. Most frequently, the electrophoretic deposition (EPD) [12,14,[39][40][41], electrocathodic deposition [15,16,20] or chemical vapor deposition (CVD) processes [42] are applied to prepare CNTs coating.…”

Carbon nanotubes are proposed for reinforcement of the hydroxyapatite coatings to improve their adhesion, resistance to mechanical loads, biocompatibility, bioactivity, corrosion resistance, and antibacterial protection. So far, research has shown that all these properties are highly susceptible to the composition and microstructure of coatings. The present research is aimed at studies of multi-wall carbon nanotubes in three different combinations: multi-wall carbon nanotubes layer, bilayer coating composed of multi-wall carbon nanotubes deposited on nanohydroxyapatite deposit, and hybrid coating comprised of simultaneously deposited nanohydroxyapatite, multi-wall carbon nanotubes, nanosilver, and nanocopper. The electrophoretic deposition method was applied for the fabrication of the coatings. Atomic force microscopy, scanning electron microscopy and X-ray electron diffraction spectroscopy, and measurements of water contact angle were applied to study the chemical and phase composition, roughness, adhesion strength and wettability of the coatings. The results show that the pure multi-wall carbon nanotubes layer possesses the best adhesion strength, mechanical properties, and biocompatibility. Such behavior may be attributed to the applied deposition method, resulting in the high hardness of the coating and high adhesion of carbon nanotubes to the substrate. On the other hand, bilayer coating, and hybrid coating demonstrated insufficient properties, which could be the reason for the presence of soft porous hydroxyapatite and some agglomerates of nanometals in prepared coatings.

Nano-sized carbon allotropes, particularly graphene (G), graphene oxide (GO), single and multi-walled carbon nanotubes (CNTs, SWCNTs, and MWCNTs) and their chemically modified derivatives are widely used in anticorrosive coating formulations. Generally, carbon allotropes acquire nanofiller property and high hydrophobicity which make them ideal anticorrosive materials. Along with various advantages, using carbon allotropes as anticorrosive materials are connected with some specific challenges including un-controlled dispersion in polymer matrixes. Chemical functionalization using covalent and non-covalent methods are widely used to enhance their dispersibility. Magnetic stirring, ultrasonic mixing, ball milling and shear emulsification are also widely used to enhance their dispersibility. Present review article describes the covalent and non-covalent functionalization of G, GO, and CNTs and their application as corrosion inhibitors in various coating formulations and aqueous phase. Chemically modified GO shows remarkable solubility/dispersibility in the aqueous electrolytes. Advantages and challenges using these materials as corrosion inhibitors have also been discussed hereincorrosion inhibitors, nanocomposites, nanotechnology, polymer matrixes and green corrosion inhibitors 1This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…The results indicated no microcracking, increased bond strength between coating layers and implants, and peeling resistance. Furthermore, the corrosion resistance and antibacterial properties of MWCNT/HAp composites were evaluated [ 94 ]. HAp/MWCNT-coated 316L SS implants were fabricated by spray pyrolysis and exhibited greater corrosion protection and corrosion current density than pristine 316L SS implants.…”

While conventional dental implants focus on mechanical properties, recent advances in functional carbon nanomaterials (CNMs) accelerated the facilitation of functionalities including osteoinduction, osteoconduction, and osseointegration. The surface functionalization with CNMs in dental implants has emerged as a novel strategy for reinforcement and as a bioactive cue due to their potential for mechanical reinforcing, osseointegration, and antimicrobial properties. Numerous developments in the fabrication and biological studies of CNMs have provided various opportunities to expand their application to dental regeneration and restoration. In this review, we discuss the advances in novel dental implants with CNMs in terms of tissue engineering, including material combination, coating strategies, and biofunctionalities. We present a brief overview of recent findings and progression in the research to show the promising aspect of CNMs for dental implant application. In conclusion, it is shown that further development of surface functionalization with CNMs may provide innovative results with clinical potential for improved osseointegration after implantation.
