中文摘要	Nanostructured surface possessing ultrahigh adhesion like "gecko foot'' or "rose petal'' can offer more opportunities for bionic application. We grow flower-like few-layer graphene on silicon nanocone arrays to form graphene nanoclusters, showing robust adhesion. Their contact angle (CA) is 164 degrees with a hysteresis CA of 155 degrees and adhesive force for a 5 mu L water droplet is about 254 mu N that is far larger than present reported results. We bring experimental evidences that this great adhesion depends on large-area plentiful edges of graphene nanosheets tuned by conical nanostructure and intrinsic wetting features of graphene. Such new hierarchical few-layer graphene nanostructure provides a feasible strategy to understand the ultra-adhesive mechanism of the "gecko effect'' or "rose effect'' and enhance the wettability of graphene for many practical applications.
