ABSTRACT:
Magnetorheological materials having a supramolecular polymer gel as a component of the carrier are disclosed. Useful supramolecular polymers for gels include those having terpyridine ligands which can participate in metal coordination bonding. The magnetizable particles of magnetorheological materials can have supramolecular surfactant-polymer coatings.
