Abstract :
Graphene films with high hydrophobic and adhesive performance were fabricated via chemical modification of graphite oxide and heat reduction processes. Irregularly stacked multilayer graphene nanosheets comprised the microstructure, whereas folding and agglomeration of graphene nanoflakes with few layers comprised the nanostructure. The resulting films showed remarkable superhydrophobic property with a static contact angle of 160.5°. Unlike many superhydrophobic materials, the obtained film is highly adhesive, allowing water drops as large as 50 μL to be inverted. Meanwhile, the film can be absolutely wet by silicone oil. This highly hydrophobic, oleophilic and adhesive performance of the graphene films could be useful in the device and biomaterial application.
