Plastic Shavings by Laser: Peeling Porous Graphene Springs for Multifunctional All‐Carbon Applications (Adv. Sci. 21/2023)

Laser‐Induced Graphene One of the keys to utility of laser‐induced graphene (LIG) is the ability to manufacture designed macroscopic geometries in a high‐throughput manner. In article number 2301208, Hyun Kim, Sukjoon Hong, Habeom Lee, and co‐workers describe a facile process that enables unprecedented control of macroscale geometries in LIG. By a single scanning of laser on a polyimide substrate, intensive pressure created by pyrolysis induces exfoliation of 3D helical LIG springs, as similar to wood or metal shavings observed in traditional machining processes. Without using any labor‐intensive, time‐consuming, and expensive processes, the presented strategy enables high‐throughput mass production of LIG springs for a wide range of all‐carbon electromechanical applications.
