Simple fabrication of biomimetic superhydrophobic lead dodecanethiolate surface with rice-like hierarchical micro/nanostructure

A superhydrophobic surface of lead dodecanethiolate with the water contact angle(CA) of 152.2°±1.2° and the sliding angle(SA) of 3.8°±1.0° was fabricated using a simple and relative inexpensive route based on our previous reported method. The procedure employed a one-pot reaction between lead salt and alkanethiolate to form a thermal stable superhydrophobic coating under mild conditions. SEM images revealed the lead dodecanethiolate surface morphology with packed aggregate "rice-like" particles of micrometer scale in length and nanometer scale in thickness. Also, Lead dodecanethiolate powder was investigated by TGA and XRD.
