The properties of nanodielectrics have been shown to be critically dependent on the way in which the materials are formulated. Large scale agglomeration often has disastrous effects on the resultant properties when conventional techniques are used to prepare the materials. In particular, the dispersion of the nanophase material has been shown to be(More)
