Adhesion is an interdisciplinary research area that focuses on understanding the forces and mechanisms involved in the bonding of two materials or surfaces at the molecular and macroscopic level. It encompasses a wide range of fields including chemistry, physics, materials science, and engineering. Researchers in this area study the interactions between surfaces, the factors that influence adhesion strength, and ways to manipulate or control adhesive properties for various applications such as in adhesives, coatings, and biomedical materials. By gaining a better understanding of adhesion, researchers aim to develop new materials and technologies that can improve the performance and reliability of adhesive systems in different industries.
