Abstract

Precise control of surfaces and interfaces is essential for the fabrication of various functional materials. Although various methods have been applied to the functionalization of surfaces, these methods are specialized for the fabrication of specific surfaces for specific purpose. In this context, a versatile, yet efficient tool for the surface manipulation is strongly desired. Here, we demonstrate a simple method of functionalizing various surfaces through a decal-like transfer of a giant nanomembrane. Control of wettability was chosen as an example, and a hydrophobic nanomembrane was transferred to various other substrates, including Si, polymer film, and metal. A drastic change in contact angle clearly indicated that the wettability of the processed material was identical to that of the surface-functionalized nanomembrane. In contrast, other physical properties such as the mechanical properties of the processed material remain unchanged. The decal-like transfer of nanomembrane will become a powerful means for the fabrication of unique functional surfaces.
