Polymer Nanocomposites for Electromagnetic Interference Shielding is the first work to cover the different carbon nanomaterial-based polymer systems for EMI shielding, enabling the development of these novel conductive polymers and their use in a range of EMI shielding contexts, such as aerospace applications. In comparison to conventional metal-based EMI shielding materials, carbon-based conductive polymer composites are light-weight, corrosion-resistant, and flexible, with good processability. However, the high proportion of carbon filler used in the most widely used polymer composites leads to a deterioration of the mechanical properties of polymer. In this book, the authors explore a new alternative-the use of polymer composites with carbon nanomaterials (such as single walled carbon nanotubes, multiwalled carbon nanotubes, carbon nanofibers and graphene) providing the required level of conductivity. The small diameter, high aspect ratio, high conductivity, and mechanical strength of CNTs make them an excellent option for creating conductive composites for high performance EMI shielding materials. Different polymers have different properties that can be used to achieve conductive composites with a variety of properties. Provides an in-depth knowledge of polymer systems using carbon nanostructures Explores the use of different carbon nanomaterials (CNT, graphene, hybrid carbon nanostructures) in conjunction with a range of polymers (polyolefins, polyurethane, polyester, etc.) Offers an applications focus, investigating uses in sectors such as aerospace and the electronics and computer industries.
