Effect of bulk deformation on rubber adhesion - ScienceDirect

We discuss the effect of bulk deformation on the surface free energy of rubber compounds and its relation to the surface damage mode. We are also aiming to relate the change in the surface free energy of rubber compounds to the roll debris formation (as defined in ) during scratching friction. 2. Experimental 2.1. Materials

Surface energy and surface tension

Surface energy - Surface tension - Definition and examples. What is the surface energy and surface tension? The surface energy is defined as the sum of all intermolecular forces that are on the surface of a material, the degree of attraction or repulsion force of a material surface exerts on another material.

Surface Energy and Wetting - Adhesive

If the liquid surface energy is significantly above that of the substrate, the substrate does not wet as well. For traditional structural adhesives to bond low surface energy substrates such as polyolefins, surface treatments have been used to raise the substrate surface energy by as much as 30% to better meet the adhesive surface energy.

Surface energy characterization of modified carbon blacks

The effects of three types of chemical treatments, i.e. as polar acidic, polar basic, and nonpolar oxidations, on virgin carbon blacks have been studied in terms of pH, acid-base surface values, specific surface area, X-ray diffraction analysis, and surface free energy.

These free radicals in the presence of oxygen can react rapidly to form various chemical functiona groups on the substrate surface. Functional groups resulting from this oxidation reaction are the most effective at increasing surface energy and enhancing chemical bonding to the resin matrix.
