Self-cleaning amphiphobic coating for degrading NO and preparation method of self-cleaning amphiphobic coating

[0039] A method for preparing a self-cleaning amphobic coating for degrading NO, the specific steps are as follows:

[0040] Step 1: In parts by weight, 7 parts of P25 nano-titanium dioxide were added to 70 parts of 10mol / L sodium hydroxide solution, and stirred for 2 hours to obtain a suspension;

[0041] Step 2: Add the suspension into a hydrothermal reaction kettle, and conduct a hydrothermal reaction at 150°C for 48 hours to obtain a hydrothermal product;

[0042] Step 3: Wash the hydrothermal product 5-6 times with dilute hydrochloric acid, adjust the pH to 1-2, and stir for 24 hours;

[0043]Step 4: filter the precipitate, wash with deionized water until neutral, add absolute ethanol to disperse for 24 hours, and obtain a suspension;

[0044] Step 5: Suction filter the suspension in step 4, and dry at 110°C to constant weight to obtain titanium dioxide nanotubes;

[0045] Step 6: Disperse 0.1 part of epoxy resin (E44) in 18 parts of absolute ethanol, stir until dissolv...
