In this work, the surface part of a single-walled carbon nanotube (SWNT) film was unzipped by a Zn/HCl sputtering process, and the wettability of this graphene nanoribbon (GNR)/SWNT hybrid film was investigated. The contact angle of water droplets on the hybrid films is similar to 113.0 degrees, which is different fromthat on a pristine SWNT film (similar to 121.8 degrees). The mechanism of this variation is discussed. Combining the unique properties of GNR and SWNT films, this kind of hybrid film has great application potential.
