Adhesions Overview. An adhesion is a band of scar tissue that binds two parts of tissue or organs together. Adhesions may appear as thin sheets of tissue similar to plastic wrap or as thick fibrous bands.
Chemical adhesion occurs when the surface atoms of two separate surfaces form ionic, covalent, or hydrogen bonds. The engineering principle behind chemical adhesion in this sense is fairly straightforward: if surface molecules can bond, then the surfaces will be bonded together by a network of these bonds.
