We have developed a simple, scalable, non-lithographic, technique for fabricating durable superhydrophobic (SH) surfaces using the fingering instabilities associated with non-Newtonian flow and shear tearing. The SH surfaces have the appearance of bristled shark skin and are remarkably durable. While flow instability is regarded as adverse to roll-coating processes for fabricating uniform films, we especially harness the effect to create the SH surface. The high viscosity of the nanotube/elastomer paste has been exploited for the fabrication. Along with their durability and self-cleaning capabilities, we demonstrate drag reduction effects of the fabricated films. |
