A method for manufacturing carbon nano tube composite film on the surface of the glass substrate, using self-assembly preparation of sulfonic silane film on glass substrate surface hydroxylation, and then the substrate in N, N dimethylformamide two carbon nanotube dispersions, deposited on the surface of rare earth modified carbon nanotube. The first glass substrate immersed in Pirahan solution under 90 DEG C for 1 hours, cleaning and drying after immersion 3-Mercaptopropyltrimethoxysilane solution, standing for 6 to 8 hours out washed, dried by nitrogen in nitrate solution, get the surface of a glass substrate with a sulfonic silane film on the substrate, then placing the suspended carbon nanotubes modified by rare earth after the liquid, at 20 to 80 DEG C standing for 4 to 20 hours, remove the wash with deionized water after washing, dried by nitrogen, was deposited on the surface of glass substrate with modified carbon nanotube composite film. The invention can reduce the friction coefficient from 0.8 to 0.1 when the film is not in the film, and has obvious antifriction effect.
