Flexible, Transparent and Conductive Metal Mesh Films with Ultra-High FoM for Stretchable Heating and Electromagnetic Interference Shielding

Highlights A transparent, conductive, and flexible metal mesh film has been developed by a low-cost, uniform self-forming crackle template and electroplating strategy. The Cu mesh films show an ultra-low sheet resistance (0.18 Ω □ −1 ), high transmittance (85.8%@550 nm), high figure of merit (> 13,000), excellent stretchability and mechanical stability. The metal mesh film can be used as a flexible heater and electromagnetic interference shielding film (40.4 dB at 2.5 μm).
