| Abstract Scope |
This study presents a method for creating effective electromagnetic interference (EMI) shields that are transparent and flexible, which is vital for the new generation of flexible electronics. By integrating laser-induced graphene (LIG) with kirigami—a technique of cutting and folding polyimide films—highly conductive 3D porous graphene is produced. The entire fabrication utilizes a single laser, which makes the direct-write process both versatile and scalable. The resulting 3D graphene is highly conductive with resistance under 1 ohm/mm and good quality with G/D ratio at 1.66 and 2D/G ratio at 0.46. The films achieve an EMI shielding efficiency (SE) over 50 dB at a low density of 0.04 g/cm^3. The kirigami process can be used to tune the SE and transparency and we achieve an SE of 20 dB while maintaining over 80% transparency, which exceeds previously reported values of 2D graphene. |
