This study presents the creation of a stable, superhydrophobic surface using vertically aligned carbon nanotube forests with a thin, conformal hydrophobic poly(tetrafluoroethylene) (PTFE) coating. The superhydrophobic surface can suspend micrometer-sized water droplets on top of the nanotube forest. The research demonstrates that the combination of nanoscale roughness from the nanotube forest and the low surface energy of the PTFE coating results in a superhydrophobic surface. This surface mimics the natural superhydrophobicity observed in lotus leaves, where hierarchical roughness and a hydrophobic surface layer work together to repel water. The PTFE-coated nanotube forests exhibit a high contact angle (170°) and stable superhydrophobicity, even for microscopic water droplets. The study also shows that the superhydrophobicity can be achieved with relatively short nanotube heights. The PTFE coating is applied through a hot filament chemical vapor deposition (HFCVD) process, which allows for a uniform and thin coating on the nanotubes. The results indicate that the PTFE coating is essential for creating a stable superhydrophobic surface, as untreated forests tend to bundle together under surface tension forces during drying. The study also demonstrates the dynamic behavior of water on the PTFE-coated nanotube forests, showing that water droplets can bounce off the surface without ever coming to rest. The superhydrophobicity is further supported by the Cassie-Baxter equation, which relates the apparent contact angle to the surface roughness and the equilibrium contact angle. The results show that the PTFE-coated nanotube forests have a high advancing contact angle (170°) and low hysteresis, indicating a stable and highly hydrophobic surface. The study highlights the potential applications of superhydrophobic carbon nanotube forests in microfluidic devices, antisoleiling or antifouling surfaces, efficient heat transfer areas, and nonbinding biopassive surfaces. The research also discusses the potential of HFCVD for functionalizing the surfaces of carbon nanotubes with various polymers, including PTFE, organosilicones, and fluorosilicones, which could be useful for dispersing and separating carbon nanotubes.This study presents the creation of a stable, superhydrophobic surface using vertically aligned carbon nanotube forests with a thin, conformal hydrophobic poly(tetrafluoroethylene) (PTFE) coating.
