Magnetorheological materials are provided comprising magnetic particles, a polymeric gel and a carrier material. The polymerization of the gel is preferentially accomplished in the presence of the magnetic particles and the carrier material. Magnetorheological materials are provided having a selected off-state viscosity and a selected on-state apparent viscosity. The method of preparing these magnetorheological materials is also provided. The carrier material, the polymeric gel and the magnetic particles are selected so that the resulting magnetorheological material has the desired off-state viscosity and on-state apparent viscosity. These materials have good dispersion characteristics, reduced settling, superior off-state viscosity and superior apparent viscosity in the presence of a magnetic field.

Os materiais de Magnetorheological são fornecidos que compreendem partículas magnéticas, um gel polymeric e um material do portador. A polimerização do gel é realizada preferentially na presença das partículas magnéticas e do material do portador. Os materiais de Magnetorheological são fornecidos tendo uma viscosidade off-state selecionada e uma viscosidade aparente selecionada do em-estado. O método de preparar estes materiais magnetorheological é fornecido também. O material do portador, o gel polymeric e as partículas magnéticas são selecionados de modo que o material magnetorheological resultante tenha a viscosidade off-state desejada e a viscosidade aparente do em-estado. Estes materiais têm características boas da dispersão, estabelecir-se reduzido, a viscosidade off-state superior e a viscosidade aparente superior na presença de um campo magnético.
