Graphene Conformal‐Coated Ceramics in Arbitrary Shape Targeting Smart Widgets

The 2D atomic structure and fascinating properties of graphene provide new opportunities for the surface‐functionalization of the traditional structural materials to meet the demands for intelligent and informational applications. Conformal coating of graphene in any arbitrary‐shape, even 3D irregular shapes, is critical to the surface‐functionalized structural materials in their actual form for practical applications. Herein, as demonstrated by ceramics, this study successfully obtains graphene conformal‐coated ceramics via rationally designed a compatible strategy with the fabrication of traditional ceramics. The graphene films show intimate adherence on the arbitrary‐shaped ceramics and exhibit uniform distribution even on the concave and convex surfaces. With a practical scalability, the present work stimulates various applications of heating devices, electroluminescent devices, and touchpads in real‐life scenarios.
