Professor Mosab Kaseem of the Department of Nanomaterials Science and Engineering has developed a multifunctional hybrid coating technology through research utilizing the Plasma Electrolytic Oxidation (PEO) technique.
This research realized both corrosion resistance and photocatalytic activity simultaneously through the surface engineering of magnesium alloys, demonstrating new possibilities for the development of next-generation smart materials.
Professor Kaseem's research focuses on designing hybrid materials that combine different types of inorganic and organic substances by using the porous structure of PEO coatings as an 'active platform.' He applied PEO technology to the surface of magnesium alloys to form a sponge-like porous ceramic layer, developing it from a simple protective film into a reactive coating layer.
By introducing Layered Double Hydroxide (LDH), metal oxide nanoparticles, and functional organic molecules into this layer, the coating's performance was significantly enhanced. The resulting coating functions as a multifunctional layer that exhibits excellent corrosion resistance while also possessing photocatalytic reactivity under visible light.
This achievement is evaluated as research that shows advanced surface engineering can transform conventional passive protective layers into intelligent, highly durable, and environmentally responsive interfaces.
The research findings have been published in world-renowned international academic journals, including 'Advanced Composites and Hybrid Materials' (IF 21.8, 1st out of 34 journals in composite materials), 'Journal of Magnesium and Alloys' (IF 13.8, 2nd out of 97 journals in metallurgy), and 'Journal of Materials Chemistry A' (IF 9.5, 63rd out of 461 journals in materials science), receiving international recognition for its excellence.
Professor Kaseem stated, "Our lab explores how advanced surface engineering can functionally evolve simple protective coatings into self-adaptive materials. I hope this research leads to sustainable material design and inspires young researchers to view surface science as a bridge connecting material stability and functionality."
Meanwhile, he has been internationally recognized for his research achievements, being named on the 'Top 2% Scientists' list selected by Stanford University and Elsevier for five consecutive years from 2021 to 2025.
