Superhydrophobic brocades modified with aligned ZnO nanorods

A superhydrophobic ZnO oriented nanorods coating on brocade substrate was prepared by a low-temperature wet chemical route, and the corresponding waterproof properties were evaluated. From wetting measurement, the modified brocades have a water contact angle of ∼152° and roll-off angle of 9° to a 10 μL water-droplet. A direct immersion of the modified brocades in water gives a strongly water-repellent behavior. The obtained waterproof brocades offer an opportunity for fabricating some special and protective drygoods.
