Novel paints for composite materials coatings used in electromagnetic shielding applications

The development of materials offering electromagnetic interference (EMI) shielding is of significant consideration, since this can help in expanding the lifetime of devices, electromagnetic compatibility, as well as, protection of biological systems. Conductive paints used widely today in electromagnetic interference (EMI) shielding applications are often based on organic solvents that can rise safety issues due to the subsequent environment problems. This presentation concerns the development of eco-friendly conductive water-based paints for use in EMI shielding applications, work partially published recently by our research team in Nanomaterials journal [2]. Graphene nanoplatelets, polyaniline emeraldine (PANI) doped with poly(styrene sulfonic acid) (PSS) or HCl or HBr and poly(3,4-ethylenedioxythiophene) poly(styrene sulfonic acid) (PEDOT:PSS) in various ratios were employed in a water base for developing the paints.
