When adhesives and adhesives are a combination of electron receptors and suppliers, electrons are transferred from suppliers(such as metals) to receptors(such as polymers), forming double layers on both sides of the interface area., That creates electrostatic attraction.

When the adhesive layer is rapidly stripped from the metal surface in a dry environment, the light and sound phenomena of discharge can be observed by the instrument or the naked eye, confirming the existence of electrostatic effect. However, electrostatic action exists only in the adhesion system that can form a double layer, so it is not universal. In addition, some scholars have pointed out that the charge density in the double layer must reach 1021 electronics/cm 2, and the electrostatic attraction can have a more obvious effect on the bonding strength. The maximum density of the dielectric-stratigraphic transfer charge is only 1019 electrics/cm2(some think only 1010-1011 electrics/cm2). Therefore, although electrostatic power does exist in some special bonding systems, it is by no means the dominant factor.
