The micro- and macroscopic structures of functional films strongly influence the critical properties such as superhydrophobicity which exhibits super water repellency with a water contact angle (CA) larger than 150o for self-cleaning and anti-microbial surfaces. However, it is difficult to achieve the structural hierarchy of two dimensional (2D) graphene for superhydrophobicity. Herein, we report the fabrication of superhydrophobic graphene/Nafion nanohybrid films by controlling the structures with respect to the chemical composition from an interpenetrating networked and compactly interlocked structure (surface area of 9.56 m2 g–1) to the hierarchical petal-like, porous structure (surface area of 413.46 m2 g–1). The superhydrophobicity of hybrid thin films with the contact angle (CA) of ~ 161o was derived from the petal-like structure with hierarchical roughness, where microscale roughness was produced in the lateral direction of hybrid sheets while nanoscopic roughness was created on the edges of hybrid sheets. Furthermore, the wettability and optical and electrical properties of hybrid thin films can be controlled by manipulating the micro- and macroscale structures through the composition dependent structural changes. This concept delineated herein envisions the development of functional films based on graphenes and their derivatives as well as the fundamental study of the correlation between the structures and physical properties of materials on a nanscale.

太浮云的研究了
居然拿石墨稀来做,,,还不如拿砖石来做了
