WebAspects of the present disclosure provide for composite structures including a bonding layer that adheres a substrate (e.g., including a polymeric composition such as rubber) to a material (e.g., including a polymer such as polyurethane). The adhesion of the substrate to the material through the bonding layer can include chemical bonds such as, but not … The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. An amorphous solid that exhibits a glass transition is called a glass. The reverse transition, achieved by supercooling a viscous liquid into the glass state, is called vitrification.
