Preparation method of oriented carbon nanotube modified ceramic material
The invention discloses a preparation method of an oriented carbon nanotube modified ceramic material, which comprises the following steps: plating a metal catalyst film on a substrate, and carrying out reduction and etching treatment on the catalyst film; growing a carbon nanotube array on the substrate in an oriented manner by adopting a chemical vapor deposition (CVD) process; a ceramic matrix is deposited in the oriented array of carbon nanotubes. According to the invention, the winding and agglomeration phenomena among the carbon nanotubes can be effectively avoided, the dispersion effect of the carbon nanotubes in the ceramic material is improved, the damage to the carbon nanotubes during dispersion is reduced, the bonding strength of the carbon nanotubes and the ceramic material is improved, and the mechanical property of the ceramic material is improved. In addition, the carbon nanotubes in the ceramic material grow in an oriented manner, so that the ceramic material has excellent thermal conductivity in a specific direction, and special and excellent thermal properties are formed.
