Abstract

For the first time, the growth mechanism of biominerals formed on plate-like nanohydroxyapatite (nHAp) electrodeposited on superhydrophilic vertically aligned multi-walled carbon nanotubes (VAMWCNT-O-2) is presented and a model for the specific growth preference is discussed. VAMWCNT-O-2 films were obtained by microwave-assisted chemical vapor deposition method and funcionalized by oxygen plasma. nHAp/VAMWCNT-O-2 nanocomposites were fabricated with a direct electrodeposition of the thin nHAp films onto the VAMWCNT-O-2 films. The biomineralized ``scaffolds{''} were obtained by soaking nHAp/VAMWCNT-O-2 in simulated body fluid for 7, 14 and 21 days. Results show that the carboxyl functional groups directly attached onto VAMWCNT tips after oxygen plasma treatment were essential for the acceleration of the OH-formation and the deposition of plate-like nHAp crystals.
