Problems solved by technology

[0007] Inorganic-organic nano-hybrid ceramic materials have good high temperature resistance and corrosion resistance. However, nano-ceramic materials are highly brittle. After a period of use, the coating will crack or even fall off, which is not conducive to the harsh working conditions. Therefore, some modifications are usually made to nano-ceramic materials, but the modified materials will cause some performance losses. For example, after epoxidation modification, the high temperature resistance performance is greatly reduced.
