Vertically aligned multi-walled carbon nanotubes (VACNT) are of particular interest in regenerative medicine. Template-induced nanohydroxyapatite (HAp) has broad prospects in applied fields of bone regenerative medicine. Thus, it becomes very attractive a combination of these two excellent materials to bone tissue engineering applications. VACANT films were produced as a thin film, using a microwave plasma chamber at 2.45GHz on Ti substrates (10mmx10mmx1mm). Superhydrophilic VACNT (VACNT-O2) films were obtained by the incorporation of oxygen-containing groups using a pulsed-direct current plasma reactor with pure oxygen. The electrodeposition of the nHAp crystals on the VACNT-O2 films will be performed using Ca(NO3)2.4.H2O (2,5 mM) + NH4H2PO4 (1,5 mM). The electrochemical measurements will be performed using a three-electrode cell coupled to an Autolab PGSTAT128N equipment. VACNT-O2 films will be used as working electrodes and the geometric area in contact with the electrolytic solution. A platinum coil wire served as an auxiliary electrode, and an Ag/AgCl electrode will be used as a reference electrode. The electrodeposition parameters will be variable with different data, such as electrolyte temperature (23-90ºC); Time (20-120 minutes); pH (4,2-7,4). Field emission gun, micro X-ray fluorescence spectrometer by energy-dispersive, X-ray diFfractogram, Raman spectroscopy will be used for characterization. (AU).
