Problems solved by technology

[0009] There are many methods for preparing tin oxide thin films, such as chemical deposition, magnetron sputtering, spray pyrolysis, spraying, sol-gel method, etc.; among these methods, sol-gel method is widely valued at present. A class of methods, because it is a fast and low-cost method for preparing tin oxide thin films in a large area, the obtained product has high uniformity, good purity, few side reactions, easy control of the reaction process, and low reaction temperature. A tin oxide film with excellent properties can be obtained on any substrate; as early as 1997, Derek D.Hass et al. of NASA Langley Research Center in the United States used a sol-gel process to coat a metal oxide film on the surface of the fiber, so that the fiber surface has a good Electromagnetic shielding properties; there are also domestic reports on the use of sol-gel method to coat metal oxides on glass fibers; but there are no reports at home and abroad on the use of sol-gel method to coat ATO on glass fibers
