Insulating electromagnetic-shielding silicone compound enables direct potting electronics

Science, Journal Year: 2024, Volume and Issue: 385(6714), P. 1205 - 1210

Published: Sept. 12, 2024

Traditional electromagnetic interference–shielding materials are predominantly electrically conductive, posing short-circuit risks when applied in highly integrated electronics. To overcome this dilemma, we propose a microcapacitor-structure model comprising conductive fillers as polar plates and intermediate polymer dielectric layer to develop insulating composites. The electron oscillation dipole polarization layers contribute the reflection absorption of waves. Guided by this, synergistic nonpercolation densification enhancement enable our composite combine high resistivity, shielding performance, thermal conductivity. Its feature allows for direct potting into crevices among assembled components address compatibility heat-accumulation issues.
