“…Various nanocomposites, including polyethylene/titania nanocomposites, polypropylene/layered silicate nanocomposites, ethylene-vinyl-acetate/layered silicate nanocomposites, epoxy/ titania nanocomposites, epoxy/alumina nanocomposites, and epoxy/zinc oxide nanocomposites [9], [10], [28]- [30] were investigated, and it was reported that space charge formation was mitigated upon nanostructuration. Specifically, ethylene-vinylacetate and polypropylene nanocomposites showed reduced charge accumulation at high fields when compared with their unfilled counterparts [29].…”

The internal electric field and potential in thin polymer film caused by injected charges were numerically analyzed and some paradoxical TSDC experimental results and the effect of internal electric field on the trap parameters obtained from TSDC measurement were discussed. It's found that, under short-circuit of the external electrodes, one zero electrical field plane and one potential peak appeared within the film and their positions depended on the spatial distribution of the space charges. The internal electric filed can vary from -3×10 7 V/m to 5×10 7 V/m in the case of a space charge density 100C/m 3 at the interface between cathode and polymer film. The large internal electric field has an important impact on the space charge transportation due to Poole-Frenkel effect, which can change the trap depth. In addition, the reversed current peak in TSDC spectrum, the reduced space charge quantity that can be measured by TSDC may all be resulted from the internal electric field and potential distribution.

“…It is found in epoxy titania, alumina and ZnO nanocomposites [3] [16], PP and EVA layered silicate nanocomposites [21] [22] [25] and LDPE titania nanocomposite [26] that space charge is mitigated by nanostructuration. Space charge is usually measured by the pulsed electro-acoustic method (PEA method), from which the electric field distribution and then the maximum field can be calculated.…”

Polymer nanocomposites possess promising high performances as engineering materials, if they are prepared and fabricated properly. It was also clarified that they could provide favorable performances as dielectrics and electrical insulation. Comprehensive reviews were given in literatures by the author firstly in 2004 and secondly in 2005. This review is based on the second paper and covers recent significant findings. It also utilizes a recently proposed multi-core model, i.e. a fine structure of "interaction zone" in order to explain various phenomena associated with nanocomposites.
