Problems solved by technology

[0003] However, the current nano-coating production method is costly and cumbersome, which is not conducive to industrialization and large-scale production.
On the other hand, the current nano-coatings are not only costly to use, but also have limited performance improvement compared to traditional coatings, and have relatively large limitations, making it difficult to further improve their performance.
