Superhydrophobic coatings made from polydimethylsiloxane and wax
Scientists recently reported the preparation of a composite suspension coating from biocompatible carnauba wax and polydimethylsiloxane, and demonstrated its superhydrophobicity and resistance to water impact.
The superhydrophobicity and mechanical stability of the coated surfaces can be controlled by adjusting the concentrations of constituent materials.
The composite suspension can be easily drop cast or spray-coated on common materials, such as glass and paper, wherein the coated surface exhibits excellent superhydrophobicity and self-cleaning property.
High resistance against water impact
Glass substrates spray-coated with the composite suspension demonstrate high levels of resistance against water impact, retaining superhydrophobicity even after the impact of 250,000 water droplets.
The study is published in: Progress in Organic Coatings Volume 136, November 2019, 105279.
