Novel magnetorheological elastomer compositions are provided. The magnetorheological elastomers (MREs) may have aligned or randomly arranged magnetizable particles in a thermoset or thermoplastic matrix. The magnetizable particles may be coated to reduce corrosion and/or improve bonding between the particle...http://www.google.fr/patents/US7261834?utm_source=gb-gplus-shareBrevet US7261834 - Tunable magneto-rheological elastomers and processes for their manufacture
