Adhesives Applications and Recent Advances IntechOpen
Jul 24 2017 · Adhesives can be defined as social substances capable to join permanently to surfaces by an adhesive process. This process involves two dissimilar bodies being held in intimate contact such that mechanical force or work can be transferred across the interface. Since their early discovery by the Egyptians—3300 years ago—intensive research efforts have been made with the purpose of

The Importance of Strong Carbon−Metal Adhesion for
Density functional theory is used to show that the adhesion between single-walled carbon nanotubes (SWNTs) and the catalyst particles from which they grow needs to be strong to support nanotube growth. It is found that Fe Co and Ni commonly used to catalyze SWNT growth have larger adhesion strengths to SWNTs than Cu Pd and Au and are therefore likely to be more efficient for supporting
