AI Technical Summary

Problems solved by technology

[0003] Most of the prior art to solve the problem of organic-machine interface adopts the method of physical interface, such as various spraying techniques, the bonding firmness of this physical interface is poor, and it is easy to fall off
Some methods that use chemical interface to solve organic-machine interface problems, such as surfactant method, silane coupling agent method, etc., mainly combine weak interactions such as coordination bond, hydrogen bond, electrostatic interaction and van der Waals force to form organic-machine interface. The inorganic interface is unstable
