Direct‐Write Laser Patterning of PDMS/Graphite Composites for Dual‐Functional Surfaces with Tunable Conductivity and Wettability (Adv. Mater. Interfaces 15/2025)

Surface Engineering In article 2500243, Hong-Ren Jiang and co-workers present a novel direct-write laser approach for creating multifunctional PDMS surfaces with tunable properties. The black laser-induced graphene controls electrical conductivity, while white SiO2 particles regulate wettability. By incorporating graphite as anchoring points, this blue laser method offers a versatile single-step platform for flexible electronics, microfluidics, and smart materials.
