Abstract
In this study, we present a strategy to fabricate durable superhydrophobic materials by employing organosilane surface-functionalized quartz sand particles. The quartz sand particles are bonded intimately with diethoxydimethylsilane and triethoxymethylsilane to enhance the mechanical properties of the materials. The obtained materials possess superhydrophobicity with the water contact angle of 158 ± 1° and self-cleaning ability. Moreover, the materials can endure the 6H pencil hardness test and also can keep stable superhydrophobicity under extreme environment conditions of immersion test and mechanical force. Scanning electron microscopy and water contact angle measurement were used to describe the morphological features and explain the obtained surface wettability. The chemical compositions of the materials were confirmed by Fourier-transform infrared spectrophotometer and X-ray photoelectron spectrometer. The appearance of the successful durable superhydrophobic material could yield a prospective candidate for various practical applications.
