Adhesion Between Rubbers and Grafted Solids

Abstract

The adhesion energy, G (at low separation velocities), between a rubber and a solid surface, is expected to increase when flexible chains, chemically identical to the rubber, are attached to the surface. This can be set up with or without chemical binding of the chains to the rubber (“bound” chains or “free” chains).

Key Words:

• adhesion promoters
• interfaces
• adhesion energy
• low separation velocity
• flexible chains
• interdigitation
• “brush” of grafted chains
• “sausage” model
• “free” connectors
• “bound” connectors
