Abstract

This study evaluated the effect of different additives such as nanocarbon compounds (0.5, 1.0, and 2.0 wt.%) with different morphologies and gelatin (Gel) (10 wt.%) on the mechanical properties of hydroxyapatite (Hap)-based nanocomposites (NCs). The NCs were prepared using the innovation process "SmartBox" based on the Internet of things (IoT), which provides process control and reproducibility, and they were characterized by X-ray diffraction, particle size distribution, transmission electron microscopy, Fourier transform infrared spectroscopy, and thermal analysis. The compressive strength tests demonstrated that the use of grapheme oxide (Hap_ GO_ 2.0 - 133 N/mm$^{2})$, and/or Gel (Hap_ Gel - 152 N/mm$^{2})$ as additives to reinforce Hap (106 N/mm$^{2})$ is more appropriate than the use of single functionalized multiwalled carbon nanotubes (Hap_ fMWCNT_ 1.0 - 110 N/mm$^{2})$ and fullerene (Hap_ Ful_ 0.5 - 106 N/mm$^{2})$.
