Disperse
« Back to Glossary Index

Disperse interactions are weak and short-range forces between uncharged molecules. Although they are only weak, without them no liquids or solids of non-polar compounds would exist. Disperse interactions therefore have a significant influence on the behaviour of matter.

The interactions are electrostatic in nature. The electron distribution of atoms and molecules fluctuates with time. This results in short-term random charge shifts, which in turn induce dipoles.

Disperse interactions are weak and short-range forces between uncharged molecules.

Although these interactions are short-range and relatively weak, they make up a large proportion of intermolecular interactions. In particular, the stability of many non-polar materials, including plastics, is based on these interactions.

Disperse interactions are weak and short-range forces between uncharged molecules.

Since there is a strong distance dependence of these forces, it is important that the binding partners are close to each other. This is an effect that is achieved by plasma treatment, fine cleaning removes impurities that act as release agents and the bare surface can form bonds. In addition, polar functional groups are introduced which, together with the disperse forces, contribute to the molecular interactions and produce better adhesion.
