A group of researchers at Drexel University and the Korea Institute of Science & Technology are creating a thin coating of a nanomaterial called MXene in order to contain ‘electromagnetic pollution’.
The proliferation of electronics in recent decades has contributed both to the volume of radiation generated and its affect on communications and broadcast receivers. This nanomaterial should ideally clean up electromagnetic pollution by containing the emissions according to Drexel.
“Shielding against electromagnetic interference typically includes encasing the interior of devices with a shield or cage of a conductive metal like copper or aluminum, or a coating of metallic plating,” explained Drexel, “And while this is effective, it also adds weight to the device and is considered a restriction on how small the device can be designed.”
“Their findings suggest that by using a thickness of 8 micrometers of titanium carbide, one of about 20 two-dimensional materials in the MXene family discovered by Drexel University scientists, they could achieve nearly 100% blockage of radiation of frequencies in the range from cell phones to radars.”
