In-situ synthesis and characterization of powdery nanocomposite “carbon nanotubes/nanoalumina”

Abstract Synthesis of in-situ composite CNTs/nAl2O3 was studied. CNTs/(5–15 wt %)nAl2O3 composite was obtained varying the initial Al-contained materials with or without calcination at 700 °C. The CNTs/nAl2O3 nanopowders were comprehensively characterized by XRD, TEM, SEM, EDX, and electron diffraction methods. The morphology of the in-situ synthesized composite CNTs/nAl2O3 was found as a net-shaped structure of nAl2O3 nanofibers uniformly distributed in CNTs with the particle size of less than 30 nm. The synthesized composite CNTs/nAl2O3 is an attractive candidate modifier material for 3D printed silumin.
