Two questions concern and intrigue many of the people occupied in various applications: Why do things stick together? Is it possible to predict which materials will stick? Any attempt to answer them leads into several apparently disparate fundamental topics of the physics and chemistry of materials. First there is a consideration of the forces that are available to confer strength, both cohesive and adhesive, and their characteristics. Then an investigation of the nature and properties of surfaces and the consequences for obtaining effective bonding. Thereafter comes a consideration of adhesives and their properties, both before, during and after ‘cure’. This leads on to the thermodynamics of surfaces and interfaces. A fresh approach considers the theoretical strengths of materials and bonds, in contrast to the observed strengths, and sources of these differences can be considered. Finally, it is possible to begin to predict adhesive properties and potential. |
