Aerospace applications experience electromagnetic interference produced by the space environment and by the materials, devices, and systems used in satellites, space shuttles, the international space station, and airplanes. The advanced materials represent a technological possibility to develop coatings that are able to offer a better shielding effectiveness against electromagnetic interference due to the possibility of controlling its electrical and magnetic properties as well as to that the size of the materials is very similar to the electromagnetic waves that it receives. In this chapter, an analysis of progress over advanced materials is presented with the aim of diffusing the role that nanomaterials have had, have and will have to increase the shielding to electromagnetic interference. Nanomaterials will protect aerospace components in the range of Hz to THz, but the huge advantage is that the range of protection can be optimized according to the technical requirements with a considerable weight reduction.
