Solar steam generation and re-condensing into water is an effective method to alleviate water scarcity caused by unreasonable water waste. This report utilizes superhydrophobic aluminum and superhydrophilic glass as the condensing system and anti-fogging unit, ensuring highly efficient collection of drinkable water. By utilizing a nanowire array and photothermal conversion membrane, the solar distiller achieves a photothermal conversion efficiency of 81%, and by surface modification, achieves superhydrophobic and superhydrophilic surface properties. The synergy of these technologies leads to a water collection efficiency of up to 66% for the solar distiller.
Solar steam generation and re-condensing into water is an effective way to lighten water scarcity caused by unreasonable waste of water. In this report, superhydmphobic, high thermal conductive aluminum and superhydrophilic glass was applied as condensing system and anti-fogging unit to ensure highly efficient process of drinkable water collection. The nanowire array of copper sulfide with nanomd array architecture guarantees strong solar absorption, which was used as photothermal conversion membrane to evaporate water. The efficiency of photothermal conversion to steam generation reached up to 81% under 1 sun illumination. Etching and surface modification was applied on high thermal conductive aluminum and glass to obtain a superhydmphobic and superhydrophilic surface nature. These three synergies of nanorod array architecture, anti-fogging glass and high-efficiency condensing system made the solar distiller a highly water collection efficiency up to 66%.
