Abstract

For the first time, the mechanism of growth of plate-like n-HA electrodeposited on superhydrophilic vertically aligned multi-walled carbon nanotubes (VACNT) is presented and a model for the specific growth preference is discussed. Results show that the carboxyl (carboxylic acid)/carboxylate functional groups directly attached on VACNT tips after oxygen plasma treatment were essential for the acceleration of the OH- formation and the deposition of plate-like HA crystals. FEG-SEM, EDX and XRD showed that a homogeneous highly crystalline HA film, stoichiometric and with preferential growth in the (002) plane direction, was formed.
