Tens of centimeter-scale flexible superhydrophobic nanofiber structures through curing process

Superhydrophobic surfaces have been fabricated for many biological and engineering applications. However, due to the delamination of the nanostructured layer from a handling layer during the fabrication process, we could not have obtained uniform nanostructured surfaces in large areas. Here, we first report tens of centimeter-scale superhydrophobic nanostructures with flexibility, cost-effective, no aging degradation and drag reduction by adopting curing processes, which have uniform superhydrophobic nanostructured surfaces on the size of 30 x 14 cm(2). Such a nanostructure could be a potential platform for many applications such as microfluidic devices for biological studies, and industrial self-cleaning products for automobiles, ships, and houses.
