Breakthrough Ultrathin Film Absorbs 99% of Electromagnetic Waves

Korean researchers develop a versatile material that enhances electronic reliability by reducing interference across multiple frequency bands.

Developed by the Korea Institute of Materials Science, the new film absorbs electromagnetic waves from 5G/6G, WiFi, and radar frequencies.
This innovative material addresses interference issues by absorbing rather than reflecting electromagnetic waves, unlike traditional shielding solutions.
The film combines magnetic composites and carbon nanotubes, achieving high absorption rates while remaining under 0.5mm thick.
Tests show the material's durability, maintaining performance even after 5,000 bends, making it suitable for flexible electronics.
The material is patented in Korea and is being applied in communication devices and automobiles, with further patents pending internationally.
