Oxygen‐Mediated Surface Engineering of 3D Porous Graphene for All‐Graphene‐Based Humidity Sensors

Abstract: Real‐world applications of graphene require reliable routes for synthesizing large‐area graphene and methods to tune its structural and electrical properties. A viable and facile route is presented for synthesizing 3D porous graphene (3PG) on PI films with tunable patterns and locations via the photon‐pen writing technique and subsequent oxygen plasma treatment. The laser power and scan speed are optimized for 3PG synthesis. The electrical properties and surface hydrophilicity are controlled via surface customization of 3PG with optimal oxygen plasma treatment duration and laser inter‐spacing. The capability of humidity sensors based on surface‐customized 3PG with hydrophobic surface is demonstrated.
