The working principle of adhesive tape mainly depends on the characteristics of its adhesive, and the adhesion between objects is realized through the interaction between molecules. Specifically:

Composition of adhesive: Adhesive tape usually consists of substrate and adhesive coated on the substrate. Adhesives can be natural or synthetic materials, and various polymers are widely used as adhesives in modern adhesive tapes. one
Bonding process: When two objects are bonded by adhesive tape, chemical bonds or physical adsorption are formed between the adhesive molecules and the surface molecules of the objects, resulting in adhesive force. This force can be van der Waals force, hydrogen bond or other intermolecular interaction force. 2
Functions of specific types of adhesive tapes: Different types of adhesive tapes, such as heat-conducting double-sided adhesive tapes, have thermal conductivity in addition to the basic adhesive function, which is due to the combination of heat-conducting materials and adhesives. three
Generally speaking, adhesive tape can achieve firm adhesion between objects through the chemical and physical characteristics of its adhesive. Different types of adhesive tapes have different compositions and characteristics according to their specific applications (such as insulation, heat conduction, etc.).
