[0042] The preparation method of modified composite snake skin specifically comprises the following steps:
[0043] (1) Preparation of ferrite nanopowder: Dissolve 3 parts by weight of ferric nitrate and 2 parts by weight of ferrous nitrate in 50 parts by weight of water, add 7 parts by weight of citric acid, disperse by ultrasonic at 1000W for 30min, heat to 40°C to evaporate the solvent, obtaining a sol; then increasing the heating temperature to 120°C to form a dry gel, taking out and igniting the dry gel to obtain ferrite nanopowder;
[0044] (2) Mixing of inorganic nano-powder: uniformly mix 3 parts by weight of AlN nano-powder and 7 parts by weight of the ferrite nano-powder obtained in step (1) to obtain inorganic nano-powder;
[0045] (3) Polydopamine modification: uniformly disperse 10 parts by weight of the inorganic nano-powder in step (2) in 50 parts by weight of ethanol solution, add 7 parts by weight of dopamine hydrochloride and 0.5 part by weight containing 2wt...

[0048] The preparation method of modified composite snake skin specifically comprises the following steps:
[0049](1) Preparation of ferrite nanopowder: dissolve 5 parts by weight of ferric nitrate and 2 parts by weight of ferrous nitrate in 50 parts by weight of water, add 10 parts by weight of citric acid, disperse by 1000W ultrasonic wave for 30min, heat to 50°C to evaporate the solvent, obtaining a sol; then increasing the heating temperature to 150°C to form a dry gel, taking out and igniting the dry gel to obtain ferrite nanopowder;
[0050] (2) Mixing of inorganic nano-powder: uniformly mix 5 parts by weight of AlN nano-powder and 7 parts by weight of the ferrite nano-powder obtained in step (1) to obtain inorganic nano-powder;
[0051] (3) Polydopamine modification: uniformly disperse 10 parts by weight of the inorganic nanopowder in step (2) in 50 parts by weight of ethanol solution, add 12 parts by weight of dopamine hydrochloride and 1 part by weight of dopamine hy...

[0054] The preparation method of modified composite snake skin specifically comprises the following steps:
[0055] (1) Preparation of ferrite nanopowder: Dissolve 4 parts by weight of ferric nitrate and 2 parts by weight of ferrous nitrate in 50 parts by weight of water, add 9 parts by weight of citric acid, disperse by ultrasonic at 1000W for 30min, heat to 45°C to evaporate the solvent, obtaining a sol; then increasing the heating temperature to 135° C. to form a dry gel, taking out and igniting the dry gel to obtain ferrite nanopowder;
[0056] (2) Mixing of inorganic nano-powder: uniformly mix 4 parts by weight of AlN nano-powder and 7 parts by weight of the ferrite nano-powder obtained in step (1) to obtain inorganic nano-powder;
[0057] (3) Polydopamine modification: uniformly disperse 10 parts by weight of the inorganic nano-powder in step (2) in 50 parts by weight of ethanol solution, add 10 parts by weight of dopamine hydrochloride and 0.7 parts by weight containing...
