Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals. High-frequency electromagnetic fields can only be shielded with conductive shells that are closed on all sides. Often, thin metal sheets or metallized foils are used for this purpose; however, for many applications, such a shield is too heavy or too poorly adaptable to the given geometry. A light, flexible, and durable material with extremely high shielding effectiveness is needed.
