27. Further in evidence for the formation of a PS-P2VP brush layer is the following. The as-synthesized particles can be dispersed in THF upon sonication but will slowly sediment. Once a small amount of BCP is added, however, the particles form stable dispersions in THF.

29. Magnetic orientation of montmorillonite (MMT)/epoxy composites has been reported, taking advantage of the magnetic susceptibility of the aluminosilicate layers in some MMTs. Thus, templating a unique orientation of lamellar BCP domains should be possible via the incorporation of a low concentration of appropriately functionalized, exfoliated MMT and magnetic alignment, in analogy to what we have demonstrated here with nanorods and BCP cylinders.
