[Asia Economy Reporter Lee Hyun-joo] Ewha Womans University announced on the 4th that a research team led by Professor Park Ji-hoon from the Department of Science Education and Chemistry Education has developed a semi-permanent nano-coating technology that can prevent eyeglass fogging. This technology has been filed for a domestic patent and commercialization research is underway. The research team succeeded in developing a silica composite material nano-coating technology by combining polyphenol substances extracted from plants with the robust 'glass film formation mechanism' of the marine organism glass sponge. The developed silica composite material nano-coating imparts superhydrophilicity to the coating surface, demonstrating excellent anti-fogging effects even with a thin coating layer of several tens of nanometers in thickness. Thanks to the sturdy glass material, the silica composite material nano-coating maintains excellent anti-fogging effects even after high-temperature treatment exceeding 300℃ and rapid temperature changes ranging from 60 degrees to minus 20 degrees. Even more remarkably, it was confirmed that the silica composite material nano-coating remains intact and continues to exhibit anti-fogging effects despite exposure to strong chemical detergents and contamination from oily substances.
