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.
