Patent ID: 7955697

Claim:
An adhesive bond between a substrate material having material having a nano-indented surface and a nano-indented solid region proximate to the surface comprised of polymer compounds with a low active surface energy in a range of fluoropolymers, and a second material deposited particle-by-particle on the nano-indented surface of the substrate material while the nano-indented surface of the substrate material is in an energetically excited state, wherein a nano-structured transition region comprising nano-composites is formed between the nano-indented substrate material and the second material in such a way that the transition region has a layer thickness between 20 nm and 20 μm and is predominantly formed of nano-composites, and wherein a ratio of substrate material to the second material in a direction transverse to the transition region changes from predominantly nano-indented substrate material in an immediate vicinity of the nano-indented substrate material to predominantly the second material in an immediate vicinity of the second material, with the nano-indented substrate material transitioning into the second material with a nano-structure.
