Abstract

Article history: A facile approach to fabricate a stable superhydrophobic composite comprising multi-walled carbon Received 7 September 2015 nanotubes and silicone rubber has been reported. Contact angle of de-ionized water droplets on the Received in revised form 2 February 2016 ◦ prepared surface was measured with the value of near 159 ; while water droplets easily rolled off and Accepted 3 February 2016 bounced on it. Surface free energy of the superhydrophobic coating was examined by three methods Available online 6 February 2016 about 26 mJ/m . The prepared film shows good stability under high stress conditions such as ultraviolet exposure, heating, pencil hardness test, attacking with different pH value and ionic-strength solutions. In Keywords: addition, remarkable stability of the coating was observed after soaking in condensed hydrochloric acid, Superhydrophobic 5 wt.% NaCl aqueous solution, boiling water and tape test. Carbon nanotubes © 2016 Elsevier B.V. All rights reserved. Contact angle Silicone rubber Surface free energy 1. Introduction surface [18–20], and vertical alignment of nanotubes or nanofibers [21,22]. Superhydrophobic surfaces are usually observable on plant In recent decade, carbon nanotubes (CNTs) have been leaves in nature.
