Electrical properties and mesostructure of carbon black-filled polymers

摘要: Abstract The electrical properties of carbon black-filled polymers are briefly reviewed. published experimental findings compared to the predictions current models related percolation theory. It is deduced that, although this theory applies qualitatively most observed behaviors, it fails give account quantitatively many others, like for example location well-known conductivity transition. One concludes that basically one may suspect model mesotructure involved in approach not fully appropriate. New results obtained by means a novel technique allowing powerful investigation connection among conducting particles throughout heterogeneous material reported. A preliminary conclusion mesostructure can be qualitative agreement with model.
