A bio-inspired synthesis strategy was conducted to fabricate superhydrophobic and superoleophilic polyurethane foam surfaces with self-cleaning properties and oil/water separation capability. In this contribution, the micro-nanoscale structure first constructed on polyurethane foam surfaces, and then the resultant surface multiscale structures were modified with low surface energy fluoroalkylsilane (FAS). Surface structures and wettability were characterized by combining environmental scanning electron microscopy and contact angle measurements. Research indicated that both surface multiscale structures and the low surface free energy coating result in the final formation of superhydrophobicity.

Inspired the sueprhydrobic and high adhesion of gecko's feet, we fabricated the carbon nanotube (CNT) film with superhydrophobicity and high adhesion for water droplet, simultaneously. The experimental results show that the contact angle (CA) of water is as high as 156o and the adhesion force reaches 50 μN, which is comparable to that of natural gecko's feet. On the other hand, the bioinspired CNT film shows high mechanical properties due to the formation of three dimensional network. Finally, this bioinspired functional CNT film is continuously synthesized by floating chemical vapor deposition (CVD), indicating the large scale CNT film can be easily obtained and supplying the promising potential practical application in no-loss water microdroplet transport.

A superhydrophobic TiO2 film with water contact angle greater than 170 on Hastelloy substrate was fabricated through simply dip-coating method from TiO2 precursor solution containing TiO2 nanoparticles with the average diameter 25 nm, followed by heat-treatment and modification with fluoroalkylsilane (FAS) molecules. The as-obtained sample was characterized by scanning electron microscopy (SEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), and water contact angle measurement respectively. Moreover, the dynamic light scattering (DLS) size distribution of TiO2 aggregated particles in the TiO2 prucursor solution containing P25 particles was evaluated by Laser Particle Sizer. It is found that the TiO2 nanoparticles in TiO2 precursor solution play a crucial role to form high superhydrophobicity. Simultaneously, the superhydrophobic TiO2 film still showed great superhydrophobicity after corroded with strong acid or alkali solutions and protected the substrate from corrosion which should be critical to the potential application in industry.
