“…The peak at 1585 cm -1 is the peaks of the voltage vibration of the MWCNTs -C=C-bonds (Kumar et al, 2018). The peaks seen at 1051 cm -1 and 1211 cm -1 show the C-O bonds in various chemical environments (Akbaba et al, 2018). It is important to connect the COOH group to the CNT to provide the ideal dispersion of water or f-MWCNTs in liquid solutions up to pH 7 (Faneca et al, 2018).…”

“…This process is carried out by joining the metal and metal oxide nanoparticles into MWCNTs. Cu, Fe, Ni, Zn, Cu2O, ZnO, SnO2 have been used to make the MWCNTs metallized, these metals were planted, grafted or stacked to the structure or to the structure surface (Akbaba et al, 2018;Kumar et al, 2018;Lassègue et al, 2017). Electrodeless deposition, sonochemical deposition, liquid impregnation, deposition under supercritic fluid, chemical vapor deposition (CVD), chemical solution route, sol-gel, chemical precipitation, diffusion, solvo-thermal, wet chemistry, thermal decomposition reaction and gamma-irradiation techniques are used to metallize the MWCNTs (Kumar et al, 2018;Lassègue et al, 2017).…”

“…MWCNTs have been grown on Cu-Fe nano-catalyst substrate. As a result of the process, catalytic recovery was observed, particularly for the Cu-Fe bilayer structure (Akbaba et al, 2018). Reinforced copper metal matrix composites (MMCs) was supported with MWCNTs and the wear behavior of this supported material has been investigated.…”

Copper/copper oxide/carbon nanotube (Cu/CuO/CNT) composite thin films were prepared by like electrophoretic deposition (EPD) method. The corbon nanotubes collacted on the Cu copper substrates were characterized by SEM (Scanning Electron Microscopy), XPS (X-Ray Photoelectron Spectroscopy) and FTIR (Fourier Transform Infrared Spectroscopy). Carbon nanotubes are functionalized to collect carbon nanotubes on copper substrate using the EPD method. It was observed in FTIR measurements that functionalized carbon nanatubes were negatively (OH -) loaded. It is shown by SEM images that cabron nanatubes are collected on copper substrate. Cu, O and C elements were observed in the XPS measurements, it was observed that the O ratio was quite high and there was CuO formation.

W ith the discovery of multi-walled carbon nanotubes (MWCNTs), it has become a desirable material in various technological applications. This material is desirable because of its unusual properties. These properties include the desired electrical, physical, optical and mechanical properties, thermal stability, large surface areas, tensile strength, and their ability to be modified according to the purpose [1][2][3][4]. Owing to this remarkable properties, MWCNTs and other forms of carbon based materials have a wide range of applications in technological applications. Drug delivery systems, biosensors, transistors, nanocomposites, nanoscale electronic devices, hydrogen storage devices, energy storage devices, compositematerials use MWCNTs and other carbon based materials (Single walled carbon nanotubes (SWCNTs), double walled carbon nanotubes (DWCNTs), graphene, Functionalization Carbon Nanotube (FCNTs), Buckypapers etc.) extensively [4,5]. The interaction of MWCNTs with different acid species causes serious modifications on the structure of the material. The changes resulting from this exposure may be beneficial and harmful according to the intended use. This interaction has been used to modify the material for purpose. Different methods such as laser vaporization, electric-arc discharge and chemical vapor deposition are used to produce MWCNTs. Very little of

“…Raman spectroscopy is a powerful technique for investigating the structure differences between p-MWNCTs and MWCNTs-PEG samples [38][39][40][41][42]. Figure 3 presents the Raman spectra of the pristine MWNCTs, MWCNTs-COOH and MWCNTs-PEG samples.…”

The paper reports an influence of treatment duration on the characteristics of multi-walled carbon nanotubes (MWCNTs) functionalised by poly(ethylene glycol) (PEG) for the first time. MWCNTs covalently functionalised with PEG (MWCNTs-PEG) are successfully prepared and characterised by several techniques including FE-SEM, EDX, Raman spectroscopy and TGA. The FE-SEM images show that an average tube diameter of the MWCNTs-PEG is increased by 21% in comparison to pristine MWCNTs. According to the TGA analysis and EDX measurements, the highest weight loss of 21.31 wt% and the highest ratio of oxygen to carbon (O/C) of 22.26 % are simultaneously achieved for the treatment time of 6 h. The results allow us to conclude that the optimum time to obtain the best functionalisation result is 6 h.
