A study about electrical treeing in different EVA-layered silicate nanostructured compounds

摘要

Electrical treeing in polymeric insulation is potentially a nano-structure dependent phenomenon. The present work is part of a preliminary study on electrical treeing in EVA-layered silicate nanocomposites having different morphology. Two parameters have been mainly considered: the treeing inception voltage (TIV) and the breakdown voltage (BDV). These parameters, especially the TIV, have shown a significant increase in the intercalated nanocomposite materials. The outcomes strengthen the concept that interface interactions due to the nanostructure can improve the treeing resistance of polymeric compounds
