The polymer can play several roles in magnetic nanocomposites  

Magnetic polymer nanocomposites can be in the form of powders and suspensions, fibers, films and multilayers, or tridimensional solids. In each of these forms, they can be used in a large number of applications accordingly with their properties. A scheme of this classification is shown in Fig. 17.2. 

They are mostly based on the use of superparamagnetic nanoparticles. Their performance is related to two elemental magnetic properties

Synthetic routes for the preparation of magnetic polymer nanocomposites. 

From the X-ray diffraction point of view, magnetic polymer nanocomposites can be considered as the mixture of a polymeric matrix and of a large set of randomly oriented very small erystals, thus their study does not introduce theoretical difficulties. However, when compared to the study of more usual crystallites of micrometric size, several praetieal drawbacks quickly appear ... 

The list of companies dedicated to the manufacture of magnetic nanoparticles and nanocomposites is very extensive. Some of them are mentioned in ref. 206. More information about publications and developments in magnetic polymer nanocomposites can be found on the websites of magnetic microspheres , and Nanoforum ,and in the books cited in refs 209-212.
