GNP-BASED POLYMERIC NANOCOMPOSITES FOR REDUCING ELECTROMAGNETIC INTERFERENCES

摘要

A process for producing GNP-based polymeric nanocomposites for electromagnetic applications such as shielding and/or absorption of the energy associated to electromagnetic fields envisages a plurality of steps that comprise: controlled synthesis, for optimizing the morphological and electrical properties thereof, of graphene nanoplatelets (GNPs) to be used as nanofillers in a polymeric matrix; selection of said polymeric matrix so as to optimize its chemical compatibility with the type of GNPs thus obtained; production by means of the solution-processing technique of GNP-based polymeric nanocomposites with dielectric permittivity and electric conductivity controlled and predictable via the equivalent-effective-medium model by calibrating the parameters of the model for the specific type of polymeric matrix and GNPs used.
