Adhesion

Adhesion is the process of sticking together the surfaces of two different materials. This term is used in various fields of science and technology, such as medicine, biology, chemistry, physics and others.

In morphology, adhesion is the sticking together of two or more cells, tissues or organs. It plays an important role in embryogenesis, tissue regeneration and other processes. Adhesion is also important for the formation and functioning of many biological structures such as skin, mucous membranes, blood, lymph and others.

In addition, adhesion is used in medicine to create artificial materials such as implants and biocompatible coatings. These materials can be used to replace damaged tissue or improve its function.

Adhesion is also used in the food industry to create coatings on foods that improve their taste, texture and shelf life. For example, bread, cheese, meat and other foods can be coated with coatings that increase their shelf life and improve their taste.

Thus, adhesion is an important process in biology and medicine, as well as in other areas of science and technology. It makes it possible to create artificial materials and coatings that improve the quality of life for people and animals.

Adhesion is the phenomenon of sticking of one solid body to another upon their contact and even separation into separate parts.

A sign of adhesion is the occurrence of intermolecular interaction forces between the surfaces of abutting bodies, i.e. joining the surfaces of joined materials to each other. As a result, the material may appear sticky.

Although, this is not an entirely accurate definition of adhesion. Sometimes the term simply means bringing two surfaces together to form a strong joint. Some adhesives are paints, sealants, adhesives, etc. — are able to provide reliable adhesion of surfaces even in the presence of a small amount of moisture between them. This is called cohesive adhesion. The ability of bodies to form intermolecular adhesion forces can be illustrated by Plato’s experiment, described in a school physics course. You should moisten one half of the adhesive tape with aromatic oils (for example, floral perfume) and try to tear it off from the other, oiled half (i.e., carry out cohesive adhesion). With good surface lubrication, the adhesive strength is almost equal to the strength of the materials themselves. And after the experiment you will be left with the same two intact tapes.
