Surface Properties of Plastic Materials in Relation to Their Adhering Performance

Abstract

Adhesion between polymeric phases like adhesives and plastic surfaces is critical in many technological and industrial applications. In the last decades much progress has been made to understand the impact of the surface properties of both phases on the adhesive strength between them. These surface properties influence processes like wetting, molecular adsorption and inter‐diffusion which determine how an interface develops into an interphase after the two materials have been brought into contact. Ultimately, the properties of this interphase determine the overall adhesion strength of an assembly. In this paper important parameters in the adhesion process will be reviewed, including methods to engineer these parameters in order to attain adhesion strengths ranging from complete release to irreversible bonding.

Effects of ion beam treatment on atomic and macroscopic adhesion of copper to different polymer materials

“…measured strength values were the same as for oxygen treated polymer surfaces. The theory of adhesion states that, provided sufficiently intimate molecular contact is achieved at the interface, the materials will adhere to each other because of the interatomic and intermolecular forces which are established between the surfaces of the two materials [14]. It was demonstrated that the mechanism of adhesion in many different bonded systems involved only interfacial secondary forces (van der Waals or hydrogen bonding) [15].…”

Hybrid Composites from Wheat Straw, Inorganic Filler, and Recycled Polypropylene: Morphology and Mechanical and Thermal Expansion Performance

“…Surface energy data allows the calculation of theoretical work of adhesion values across an interface between fibers and another material [14,15]. The surface free energy was calculated according to the Lifshitz-van der Waals or Lewis acid/base theory [5,16,17]:…”

Influence of Ultraviolet Radiation Exposure Time on Styrene-Ethylene-Butadiene-Styrene (SEBS) Copolymer

“…Any consideration of adhesion mechanisms requires information regarding the physical and chemical properties of surface adhesion, or separation in the case of surfaces where adhesion has failed during use or as a result of mechanical testing [31][32][33][34]. There are a number of surface characterization techniques that can be used to investigate adhesion mechanisms and resistance to adhesion.…”
