Adhesion mechanisms refer to the processes that allow different materials to stick together. This can occur through various forces, such as van der Waals forces, hydrogen bonding, and electrostatic attraction. These forces enable materials to bond at their surfaces, which is crucial in applications like gluing, taping, and coating. Different factors influence adhesion, including surface roughness, cleanliness, and the presence of contaminants. For instance, a rough surface can increase the contact area, enhancing adhesion. Additionally, the chemical properties of the materials involved play a significant role in determining how well they adhere to each other.
