Polymer Film Can Limit Electromagnetic Interference

Engineers at the University of California-Riverside have developed a film incorporating a nanomaterial filler that reportedly provides an effective shield against electromagnetic interference.

According to an article posted in February to the website of Engineering and Technology (E&T), the film developed by the engineering team consists of composites synthesized with one-dimensional van der Waals materials, which “exfoliate” into needle-like structures. Testing showed that the resulting composite film provides “exceptional” shielding against electromagnetic radiation in the GHz and sub-THz frequency ranges.

Equally important, the chemical process used to produce the film can reportedly be quickly scaled for mass production of these materials.
