In this chapter, we consider the effect of different types of coatings and shells on magnetic particles. By grafting different kinds of coating onto magnetic particles many typical difficulties for magnetic suspensions, such as corrosion and flocculation, can be overcome. The coating effect on three different systems magnetorheological fluids (MRFs), ferrofluids (FFs) and magnetorheological elastomers (MREs) is discussed in detail and different coatings are compared for each system. The coatings are further categorized based on applications with a few special cases, which are highlighted giving emphases to the applications and a comparison to uncoated particles. Lastly, the synthesis and grafting of coatings among coating characterization techniques are mentioned, followed by conclusions and some remaining problems which coatings and shells could potentially solve.
