“…The peaks of the modified SWCNTs and modified MWCNTs shown in Fig. 2 were most likely caused by the formation of carboxylic acid groups, which contributed to the good dispersion of CNTs 23) . It is noteworthy that there was a difference between SWCNTs and MWCNTs when they directly interacted with collagens; specifically, SWCNTs had a stronger affinity for collagen than MWCNTs (Figs.…”

This study developed carbon nanotube coatings for the dentin surface and investigated the bonding strength and the in vitro antibacterial properties of carbon nanotube-coated dentin. Single-walled carbon nanotubes and multi-walled carbon nanotubes were first modified and then characterized using Fourier-transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. Second, dentin samples were coated using either single-walled carbon nanotubes or multi-walled carbon nanotubes and observed under a scanning electron microscope. Then, the shear bonding strength and antibacterial properties of the dentin samples were tested. The results showed that both modified single-walled carbon nanotubes and multi-walled carbon nanotubes formed a stable coating on the dentin surface without affecting the shear bonding strength. Moreover, the antibacterial properties of the single-walled carbon nanotube-coated samples was obviously superior to those of the multi-walled carbon nanotubecoated samples. Consequently, single-walled carbon nanotube coating may be an antibacterial agent for potential application in the dental bonding field.

“…The acid solution was filtered using centrifuging and the obtained products were washed with distilled water to pH 7 through paper filter. Finally, obtained functionalized CNTs (fCNTs) were dried in a vacuum oven at 60 o C during 48 h [2]. The results show that CNTs were functionalized successfully through the acid treatment process by the presence of carboxylic acid groups on the surface of CNTs in FT-IR spectra [22].…”

“…These materials are widely used because of the high corrosion resistance ability and good biocompatibility. Despite their successful use but in some case for their long term clinical application, these materials can corrode in the biological environment like human body fluids [2]. To solve this problem, modification the surface of these materials by the coatings which have biocompatibility as well as improvement of some properties like faster bone healing are new interesting researches.…”

Abstract. The coatings of hydroxyapatite/functionalized carbon nanotubes (HAp/fCNTs) were successfully synthesized on the surface of 316L stainless steel (316L SS) by electrodeposition. To improve the dispersion of CNTs into the electrolyte, CNTs were functionalized in the mixture of 67 % HNO 3 and 98 % H 2 SO 4 before electrodeposition coatings to form fCNTs. Different amounts of fCNTs were incorporated into the apatite coatings by adding fCNTs into the electrolyte solution. In this study, Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and mechanical techniques were used to analyze characteristics of HAp/fCNTs coatings. The results show that the HAp/fCNTs nanocomposite coatings contain single phase of HAp and CNTs with the coating thickness of 6.9 µm and the amount of fCNTs in the coatings is 6.95 %. With the presence of fCNTs in HAp coatings, the solubility of the coatings decreases in comparision with pure HAp coatings.
