Abstract
The main problem for nanocomposite synthesis is still to achieve a good dispersion and distribution of nanoparticles in the host material. In most cases this requires surface treatment of the filler material to improve compatibility with the usually dissimilar host material. Besides the fillgrade, particle type, size, aspect ratio, and surface modification all alter the properties of a nanocomposite. The synthesis method itself also has an effect on the microstructure and, therefore, dielectric behavior of nanocomposites. Finally, it is important to control all variables and minimize moisture ingress during preparation and processing of nanodielectrics, since contaminants and moisture degrade the dielectric properties of nanocomposites considerably. © 2013/IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
