Electromagnetic interference (EMI) from unwanted electromagnetic fields can interrupt, obstruct, or degrade the effective performance of electronic devices. Traditional EMI shielding is achieved with vacuum deposited metals that are susceptible to corrosion and delamination. Metal screen EMI shielding is heavy, rigid, and does not exhibit uniform shielding over a range of frequencies. For aerospace and automotive applications, a more robust and lightweight shield is needed.
Eikos’s Nanoshield® coating has demonstrated the ability to significantly reduce broad spectrum electromagnetic interference. Because Nanoshield is a printable and conformal coating, any surface can be coated without the need for a vacuum chamber. By using low density carbon nanotubes instead of metals, Nanoshield can offer significant weight savings over traditional EMI shielding.
We have tested our materials from 50 MHz to 40 GHz and found uniform and strong shielding across all wavelengths. Nanoshield has shielding effectiveness in excess of 60 dB. Invisicon® coatings have a shielding effectiveness of greater 20 dB while maintaining transparency in the visible and near infrared regions.
