ABSTRACT = {Magnetorheological fluids (MRFs) is a smart fluid system that exhibits swift and reversible
alterations in their rheological characteristics when exposed to an external magnetic field. MRFs
are used for applications in various areas, including automotive systems, robotics, aerospace,
and civil engineering. The performance of MRFs depends on the behavior of the dispersed
magnetic particles, necessitating thoughtful consideration of particle traits to optimize fluid
performance. Carbonyl Iron Powders (CIPs), high purity iron (>98%) reduced from penta carbonyl
iron, are widely employed in MRFs due to their exceptional magnetic characteristics. Nevertheless,
the innate surfaces of CIPs tend to conglomerate, leading to compromises in fluid stability and
rheological performance. To overcome the challenges, an intensive research has been devoted
to advancing surface modification techniques that augment the dispersion, stability, and overall
functionality of MRFs based on CIPs. This review describes the comprehensive approach to
surface modification of CIPs for highly stable MRFs. We discuss the various surface modification
methodologies that have been explored to optimize the behavior of carbonyl iron-based MRFs.
Coating techniques, surfactant functionalization, magnetic coatings, and emerging approaches
such as nanocoatings and electrochemical modification are also summarized. Moreover, insights
into potential applications and future prospects of these modified MRFs are provided.},
