Abstract

In recent years, extracting water from the air in hot and humid areas has been studied as a clean and optimal way to supply fresh water. In this research, painted steel surfaces were modified by vacuum plasma, and hydrophilic and hydrophobic grooves were made on them in millimeter scale. Then, by building a steam reactor, the parts were tested to extract water from the air and it was observed that modifying the surfaces increases the amount of water produced several times. Next, the optimal thickness of the paint on the steels was determined.
