Wettability of graphene nanoribbon/single-walled carbon nanotube hybrid film
Abstract
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 ∼113.0°, which is different from that on a pristine SWNT film (∼121.8°). 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.
