Abstract

We report on a simple and large-scale method for the fabrication of mechanically durable superhydrophobic coatings via electrostatic powder spray of aerogel micro particles on the fibrous substrates. The coatings are obtained by dip-coating fibrous substrates in silicon rubber/toluene solution, followed by the electrostatic spray of aerogel micro particles on the samples. The method is applicable to a large number of fibrous substrates with different pore sizes. Depending on the silicon rubber solution concentration, it is possible to obtain surfaces with hierarchical morphology. The wetting behavior dependent on the concentration of silicon rubber/toluene solution can provide coatings with static water contact angles (160°–168°) and sliding angles (3°–21°). Fibrous surfaces obtained were characterized by scanning electron microscopy and static water contact angle measurement. Also, mechanical durability of the surfaces was examined using high pressure airflow, sandpaper abrasion test, and water static pressure.
