Adhesives
For a long time, I have been aware that the topology of surfaces affect the adhesion of adhesives. I also have been aware that the surface topology also affects adhesion and here is a patent that embosses a surface microstructure to enhance adhesion. Another interesting feature of this patent is that tiny channels facilitate the removal of contaminants which also enhances adhesion.
