Description

technical field [0001] The invention relates to a method for preparing a carbon nanotube composite film, in particular to a method for preparing a sulfonic acid silane-rare earth modified carbon nanotube composite film on the surface of a glass substrate. It belongs to the 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. Due to the influence of size effects in micro-machines, micro-friction and wear and nano-film Lubrication has become a key issue, which can be solved by preparing self-assembled nano-films by self-assembly method. Compared with other thin-film preparation technologies, self-assembled thin-film technology is operable and adaptable, and has broad application prospects. [0003] Carbon nanotubes are the most typical one-dimensional nanomaterials, whi...
