There is chemical reason behind it. Interlocking is the reason for the friction between rough surfaces. In case of super smooth surfaces, interlocking can't take place.
Chemically, when two super smooth surfaces comes in contact with each other, their chemical structures disturbs.
Then their outer surface shells get merged into one another so they oppose relative motion, hence friction increases.

Friction can be increase by making surface more and more smooth as because Friction is the force that opposes the motion of an object. Interlocking is the reason for the friction between rough surfaces. In case of super smooth surfaces, interlocking can't take place.
