The invention discloses an aluminum nitride ceramic coating carbon nanotube with high temperature resistance and excellent thermal-oxygen stability as well as a preparation method of the aluminum nitride ceramic coating carbon nanotube. The preparation method of the aluminum nitride ceramic coating carbon nanotube comprises the following steps: mixing a polarity solvent with poly(alkyl aluminum) and a non-polarity solvent with an organic carbon source to obtain a mixture I, placing the carbon nanotube into the mixture I, and carrying out ultrasonic treatment; slowly volatizing the solvent at given temperature, orderly depositing poly(alkyl aluminum) and organic carbon source on the surface of the carbon nanotube, and then carrying out the precursor splitting decomposition and ceramic treatment to obtain the aluminum nitride coating carbon nanotube. The oxidization weight loss of the aluminum nitride coating nanotube in an air atmosphere at the temperature of 750 DEG C is less than 10 percent, and the retaining rate of the carbon nano-tube at the temperature of 1000 DEG C reaches up to 90 percent; the process is convenient to operate, low in cost and suitable for being applied in the field of nano devices.
