The Study of Magneto-Active Polymer Composite Physiochemical Characteristics Using Petroleum Based Oil as a Dispersing Aid

Rubber is a natural polymer of Isoprene which has elastic properties and it undergoes long
range reversible extension. Magnetorheological fluids are known to be used in shock absorbers,
dampers as well as isolators. Researchers have also studied the potential of these fluids to be
used in various industries. However, the limitation that they faced was due to the substance
being formed in a fluid state. It is believed that by forming a solid polymer composite,
numerous applications can benefit from the characteristics that it may possess. Rubber is a
natural polymer of Isoprene which has elastic properties and it undergoes long range reversible
extension. Rubber is also known as an elastomer that inhibits the ability of being magnetised.
This is made possible by combining the polymer elastomers with magnetisable elements such
as carbonyl iron particulates. In this report, we studied the physicochemical characteristics of
magnetorheological elastomers which consists of rubber and carbonyl iron particulates using
different types of petroleum based oil as a dispersing aid. In this case, we are using natural
rubber (NR) as a matrix as well as carbonyl iron particles as the magnetisable element that
would allow the presence of magnetorheological effect.
