A proper and controlled filler dispersion is the goal of each compound, and nanodielectrics are not an exception for this purpose. A method to avoid agglomeration and ensure a standard particle dimension is presented in this work. Graphene oxide has been dispersed into a thermoplastic polymer starting from standardized building-blocks made of polymeric matrix with a single controlled nano-interface of graphene oxide inside. Electrical properties, such as space charge accumulation, permittivity and conductivity, of the nanodielectric have been investigated and a hypothesis on charge carrier motion inside is proposed.

Abstract
A proper and controlled filler dispersion is the goal of each compound, and nanodielectrics are not an exception for this purpose. A method to avoid agglomeration and ensure a standard particle dimension is presented in this work. Graphene oxide has been dispersed into a thermoplastic polymer starting from standardized building-blocks made of polymeric matrix with a single controlled nano-interface of graphene oxide inside. Electrical properties, such as space charge accumulation, permittivity and conductivity, of the nanodielectric have been investigated and a hypothesis on charge carrier motion inside is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
