Embodiment 1

[0018] Carbon nanotubes: multi-walled carbon nanotubes produced by Shenzhen Nanoport Co., Ltd.

[0019] Firstly, the glass substrate is pretreated, and the glass substrate is treated with hydroxylation. Treatment method: place the glass substrate in a volume ratio of 98% concentrated sulfuric acid: 30% H 2 o 2 = 1:1 solution at room temperature for 1 hour, then ultrasonically cleaned with deionized water for 20 minutes, placed in a dust-proof device and dried in an oven. There is no special requirement for the drying temperature. Immerse the treated glass substrate in the prepared aminosilane solution, let it stand for 12 hours, wash it with anhydrous methanol and deionized water after taking it out, dry it with nitrogen, and place it in a solution containing phosphorus oxychloride and 2, 3,5-collidine was reacted in a cyanide solution for 20 minutes, and after taking it out, it was washed with a large amount of deionized water, so that phosphoric acid groups were assembled ...

Description

technical field [0001] The invention relates to a preparation method of a carbon nanotube composite film, in particular to a preparation method of a glass substrate surface self-assembled phosphoric-based silane-rare earth modified carbon nanotube composite film. It belongs to the technical field of film preparation. Background technique [0002] The development of modern mechanical science shows the trend of mechatronics, ultra-precision and miniaturization. The gap between friction pairs of many high-tech devices is often at the nanometer level. Because micro-machines are affected by size effects, micro-friction and wear and nano-film lubrication It has become a key issue. At present, a self-assembled film can be prepared on the surface of a single crystal silicon substrate by a self-assembly method to improve the anti-friction and anti-wear properties of the surface of a single crystal silicon substrate. Compared with other thin-film preparation technologies, self-assemb...
