Clear conductive flexible films provide high electromagnetic shielding from 2 to 18 GHz
These ultrathin, flexible films use the latest nanotechnology to provide high levels shielding effectiveness while remaining optically clear, for use in commercial and industrial electronic applications requiring transparency for shielding materials. The AC2ES materials can be flat or shaped into three-dimensional (3D) forms, and are available in sheets or rolls with conductivity between 0.1 and 6.0 Ω/square, 70% to 80% transparency, and shielding effectiveness (SE) of 20 to 40 dB from 2 to 18 GHz.
AC2ES shielding materials are ideal for a wide range of applications requiring shields with optical clarity including transparent windows, transparent heaters, RFID tags, wearable electronics, thin film devices, and transparent antenna patterning. The materials can even be transferred to glass and other substrates for use as transparent antennas in wireless electronic products, including in Bluetooth, cellular, and near-field-communications (NFC) devices.
The AC2ES shielding materials provide high SE levels up to 18 GHz and are available in 100-μm thin-film form. The secret of these materials is in the use of highly conductive nanoparticles that are only 5 or 10 μm thick and almost invisible to the eye. This achieves high levels of EMI shielding while remaining optically transparent.
