Interaction of carbon nanotubes coatings with titanium substrate
Abstract
The aim of this study was to evaluate the impactof multi-walled carbon nanotubes (MWCNTs) after chemicalsurface functionalization on the interaction with a titaniumsurface. Two kinds of MWCNTs differing in terms ofconcentration of functional groups were deposited on the Tisurface using the electrophoretic deposition method (EPD).The study has shown the detailed analysis of the physicochemicalproperties of this form of carbon nanomaterialand received on their base coatings using various techniques,such as scanning electron microscopy (SEM), confocalmicroscopy, X-ray photoelectron spectroscopy (XPS)and Raman spectroscopy. The adhesion of the MWCNTscoatings to the Ti surface was determined using the sheartest method, according to standard ASTM F-1044-05.These results indicated that one type of MWCNTs characterizedby a higher concentration of functional groups hasbetter adhesion to the metal surface than the second type.Analysis of the MWCNT–metal interface using Ramanspectroscopy and SEM and STEM indicates the presenceof phase built of MWCNT and TiO2.This phase could be atype of nanocomposite that affects the improvement of theadhesion of MWCNT to the Ti surface.
