Abstract
A simple and effective method for preparing superhydrophobic conductive wood surface with super oil repellency is presented in this paper. Silver nanoparticles (Ag NPs) were prepared on wood surfaces by the treatment with AgNO3, followed by a reduction treatment with glucose to generate a dual-size surface roughness. Further modification of the surface coated with Ag NPs with a fluoroalkyl silane led to a superhydrophobic surface with water contact angle of 155.2°. This surface is also super repellent toward motor oil with the maximal contact angles around 151.8°. Interestingly, the dense Ag NPs coating on the surface is electrically conductive. The presented multifunctional coating could be a commercialized for various applications, especially for self-cleaning and biomedical electronic devices.
