چکیده
Abstract Roof leakage is a common phenomenon on rainy days and makes residents uncomfortable. Superhydrophobic materials are promising candidates to protect grass houses from rainwater. However, mechanical weakness, chemical corrosion, UV light sensitivity the three main challenges restricting these nonwetting wider application in real life. Herein, we developed an inorganic–organic superhydrophobic paint (IOS-PA) for preparing waterproof house. IOS-PA not only showed robustness anticorrosion but also displayed self-healing properties, anti-icing high low temperature (150 °C −196 °C) resistance. Photocatalysis was achieved with IOS-PA, as demonstrated by organic matter (Nile red, methyl blue, orange) degradation. Moreover, extremely long-term resistance, i.e., resistance irradiation (365 nm, 5.0 ± 0.6 mW/cm 2 ) 100 h ambient sunlight 8640 (1 year), caused conflicting properties of superhydrophobicity photocatalysis coexist further accomplishing self-cleaning removal both dirt particles contamination. Specifically, house coated exhibited favorable indicating potential ensure comfortable living conditions people undeveloped areas, even days. With variety excellent characteristics, believe, advantageous scalable production practical reality.

To meet stringent limit-of-detection specifications for low abundance target molecules, a relatively large volume of plasma is needed for many blood-based clinical diagnostics. Conventional centrifugation methods for plasma separation are not suitable for on-site testing or bedside diagnostics. Here, we report a simple, yet high-efficiency, clamshell-style, superhydrophobic plasma separator tha...

BACKGROUND After comprehensive study of various superhydrophobic phenomena in nature, it is no longer a puzzle for researchers to realize such fetching surfaces. However, the different types of artificial surfaces may get wetted and lose its water repellence if there exist defects or the liquid is under pressure. With respect to the industry applications, in which the resistance of wetting tran...
