Problems solved by technology

However, this invention also has certain defects: its scratch resistance is not very good, and the scratch resistance refers to the resistance to external force and the deformation absorption capacity of the material when the material is subjected to external force, and when the resistance is as small as this When the deformation absorption (plastic deformation) cannot be restored to the original state, the surface of the substrate will be damaged and scratches will occur. The scratch resistance performance is mainly related to the hardness and friction coefficient of the material. The higher the hardness and the lower the friction coefficient, the better the resistance. The better the scratch performance, while the invention is not very ideal in terms of hardness and coefficient of friction
