Abstract: The present invention relates to core-corona type organic-inorganic hybridized nanoparticles having super water repellency, anti-staining properties, anti-bacterial properties, and oil repellency and a method for producing the same. Conventionally, a fluorine-based water-repellent material shows an excellent water-repellent effect. However, it is difficult to paint a coated surface with the material and adhere the material to the coated surface, and there is a price burden. An attempt was made to apply the water repellency of silicone to fiber. However, due to the weak coating performance of fiber, silicone is easily peeled off, and it is difficult to apply silicone to the fields of clothes that require frequent washing. It is urgent to develop a coating agent that does not peel off even after frequent washing and at the same time has super water repellency, anti-staining properties, anti-bacterial properties, and oil repellency. To this end, core-corona type organic-inorganic hybridized nanoparticles and a method for producing the same are suggested, wherein the core-corona type organic-inorganic hybridized nanoparticles comprise titanium dioxide (TiO_2) nanoparticles, quaternary silane, water-repellent/anti-staining additives or zinc oxide (ZnO) nanoparticles, quaternary silane, water-repellent/anti-staining additives. Accordingly, the nanoparticles have a self-cleaning ability in that surfaces of the same gather almost no dust and contaminants can be easily removed, and has an anti-bacterial effect against germs. Super water repellency, anti-staining properties, anti-bacterial properties, and oil repellency of the nanoparticles can be improved by 80% as compared to an existing case. The core-corona type organic-inorganic hybridization nanoparticles can be mass-produced through a systemized manufacturing method. The present invention can be widely applied and expanded to fields such as surface materials including military use, transportation equipment, construction fields, automobiles, medical treatment, energy, and textile (leather) displays. Accordingly, the present invention can increase national technology by 2-4 times and increase national revenues.
