Prof. Woonbong Hwang (ME) has successfully industr-ialized the manufac-turing technique of hydrophobic nano-surface structure by adopting “Lotus effect”, a phenomenon in which a water droplet slides down a lotus leaf, maintaining its shape due to numerous projections on the surface allowing the leaves to be hydrophobic in nature.
This technique has always been a source of attraction since it can be integrated into a plethora of fields, but products man- ufactured from this technique are still very rare since it does not work well on 3D structures.
In order to apply this technique to practical matters, Professor Hwang used a hydrophobic surface treatment evaporator, which inhibited the formation of bacteria. When the self-cleaning effect of a hydrophobic surface is used in a humidifier, it no longer needs to be cleaned, making it more convenient and hygienic.
“For the past 10 years I have put imm-easurable effort into industrializing this technique” mentioned Prof. Hwang, who is determined to develop a robust design for an oil-separating system and an evaporator for car air-conditioners.
