Adhesion

Adhesion is a process in which two surfaces stick together and resist separation. This process is critical for a variety of uses, such as in manufacturing, construction, and transportation. Adhesion occurs due to attractive forces between molecules on the two surfaces, including chemical bonds, electrostatic forces, and physical interactions. These forces can be strong enough to resist shearing and stress, thus allowing two materials to remain adhered even under extreme conditions. Adhesion is also used extensively in medical applications, such as wound dressing and surgical tapes, as it allows materials to remain attached while still allowing skin to breathe. Adhesion is a fundamental process in the natural world and plays an incredibly important role in modern technological advancements.
