The silica/silane system is widely used in the rubber industry. A disadvantage of the current system is that once the relatively stiff covalent sulphur bridge of the silica/silane/polymer connection is broken, there is no possibility to reconnect. As a consequence, a completely different coupling concept was considered, mimicking the Velcro-like system known in nature. Following this concept, an alternative type of rubber/silica coupling based on physical entanglements and steric hindrance was developed. The tangled rubber macromolecules act as molecular loops, and relatively long elastomer brushes grafted on the silica surface act as molecular hooks.
