Femtosecond laser preparing patternable liquid-metal-repellent surface for flexible electronics
Abstract(#br)Hypothesis(#br)Controlling the wetting behaviour of gallium-based liquid metal is highly desired for soft electronics applications. Currently, achieving durable and patternable liquid-metal-repellent surfaces by a simple and flexible method is challenging. The femtosecond laser has a remarkable ability to modify the morphology and wettability of a solid surface.
