Pressure-Proof Superhydrophobic Films from Flexible Carbon Nanotube/Polymer Coatings

In this paper, we report a simple and inexpensive method for fabricating stable superhydrophobic films from flexible carbon nanotube (CNT)/polymer coatings. The CNT/polymer coatings, which do not contain any fluorinated compounds, maintain their superhydrophobicity after bending and pressing and display excellent environmental stability. Furthermore, these superhydrophobic films can be coated onto glass, metals, and polymers, resulting in water-repellent, self-cleaning surfaces exhibiting high water contact angles. Such superhydrophobic coatings have potential applications in bioseparation, microfluidic devices, liquid transportation, and nonwetting surfaces.
