Abstract

The present invention relates to an eco-friendly and simple super-hydrophobic coating method that does not use harmful substances and special equipment. Coating according to the present invention may be performed as a single process without special equipment, and because only eco-friendly materials are used, the coating material may be easily used and discarded. In addition, even a three-dimensional pipe or a heat-exchanger having a complex shape may be modified to have super-hydrophobicity by applying the present coating, and a super-hydrophobic metal filter may be manufactured and used for oil-water separation. As a result, the present coating method is eco-friendly, simple, and applicable to various substrates, so it has great potential for application in various industries.
