The prerequisite of the equilibtium is the rather labile C-I bond of the CH2-CF2-I end group. This labile end group may also be used for modification of the polymer, for example, to an azide end group, which may subsequently be used for reactions with alkynes or for functionalization of carbon black nanopartides. 

Of course, clay particles are not the only nanofiDers used today. Other nanofillers include carbon particles (carbon black and carbon nanotubes), various inorganic oxides (zirconia, titania, silica, etc.), metal nanopartides (gold, silver), and some other, more exotic ones (e.g., polymeric nanopartides such as dendrimers). In general, we can distinguish nanopartides by... 

Hybrid composite sj tems that comprise mixtures of different filler types guarantee great versatility in capturing preferred electrical prop)erties combined with additional desired properties. For example, the electrical properties of carbon black/poljTner composites were enhanced significandy by the addition of just a small fraction of the more expensive CNTs. Similarly, numerical simulations by Rahatekar et rtf show that addition of spheres to a fiber system does not modify the percolation threshold of the fiber system significantly when the fraction of spheres is small, as the contribution of the fibers in the overall network fonnation is dominant. These studies suggest that hybrid composites can combine rodlike fillers to control the electrical properties and spherical fillers to modulate the mechanical, thermal, or optical properties. The possibilities are even further extended by the opportunities presented by combining disaete nanopartides with continuous fiber composites.
