Abstract Magnetic polymer nanocomposites have attracted broad interest for hyperthermic cancer treatment because they are non-toxic, biocompatible, and can be remotely heated by alternating magnetic fields. The magnetic induction heating behavior provides a great benefit in biomedical applications, such as targeted drug delivery, and magnetic separation. In situ formation of an organic or polymer layer on their surface is one of the efficient methods for decreasing the aggregation between the nanoparticles, as well as providing functionality on the surface and allowing further functionalization with drugs and therapeutic agents. The most challenging task in hyperthermia is to maximize the specific absorption rate (SAR) with a lower ferrofluids dose. Magnetic nanoparticles coated with polymer layer combine the unique magnetic properties of multi functional nanoparticles with self heating property. In addition, it is easier in preparation by a one-pot process. The formation of the nanoparticles with a higher SAR makes it a promising in hyperthermia cancer treatment. 1. Introduction The outstanding potential of magnetic polymer nanocomposites stems from the ability to obtain structures with the combinations of properties that neither individual material possesses. It is possible to synthesize these nanocomposites in desired shape and size with controlled properties of stability, surface area, magnetic, optical, and catalytic properties. The easy separation and controlled
