What is Magneto-rheological fluid ?

Magneto-rheological fluid (MRF) is a type of smart material whose rheological properties (e.g. Viscosity) can be rapidly varied by applying a magnetic field. It is a free-flowing liquid state in the absence of a magnetic field while its viscosity increases on application of magnetic field. MRF can be controlled  (increased or decreased) with the strength of the magnetic field. The MR Fluid shifts from solid to the liquid state and the other way round quite quickly. Thus, it helps in making the buildings flexible, which allows them to adapt with any of the external forces.

Components of Magneto-rheological Fluids:

Magneto-rheological Fluid is processed by making use of three prime ingredients:

• the carbonyl iron particles that are also known as the ‘soft’ particles of iron that have a diameter of 3-5 micrometres
• additives to enhance the viscosity and fluidity of the material, helps the particles to remain suspended in liquid, which also helps in reduction of the pace of gravitational settling of the particles of iron
• Also, we make use of hydrocarbon oil as a carrier liquid for producing the MR Fluid.

Application of the MR Fluids:

The MR Fluids can be used in various industries, which involve:

• Automotive Industry
• For the seismic protection of the buildings
• It is used in the washing machines
• MR Fluid is used in medical science for manufacturing of the prosthetic knee
• For the preparation of Artificial Muscles
• For polishing the devices
• Used in Clutches and Brakes
• Used in hydraulic valves
• MR Fluid is now being used as Robot Blood

Why is Magnetorheological Fluid in demand?

MR Fluid is a whole new sensation in the market and has made a remarkable mark in the industry. The experts suggest that the demand for MR Fluid will grow exponentially in the upcoming future.

The demand for MR Fluid is increasing for robotics, which is being used in the braking and damping systems. Smart fluid as it sometimes called is used in the fields of automotive, engineering, medicine and construction. Magneto rheological (MR) fluid technology has been proven for many industrial applications like shock absorbers, hydraulic systems, actuators, etc.

Below demonstrates a major development in our break grade MR Fluid.
Apart from parameters like, rheology, flash point, density, state retention is most important.

This video from our lab demonstrates how fast our GO (Graphene Oxide) based MR Fluid maintains its retention time when the magnetic field is applied and released. Sustainable performance requires synthesis and stability of the magnetic field.
