  • Publication number: 20160326048
    Abstract: The present invention relates to a glass having a surface with improved water-repellency or hydrophobicity and low reflectance, and a fabrication method thereof. A technology is employed, in which a thin film containing silicon or silicon oxide is formed on the glass surface, the nano-structures are formed by selective etching treatment using a reactive gas such as CF4 or the like to provide superhydrophobicity and low reflectance properties, and a material with low surface energy is coated onto the nano-structures. The fabrication method of the low-reflective and superhydrophobic or super water-repellent glass may execute deposition and etching processes for the glass having the superhydrophobicity and the low reflectance, and provide excellent superhydrophobicity and low reflectance to the surface of the glass which was difficult to be treated. Also, the method is sustainable due to non-use of a toxic etching solution during these processes.

  • Patent number: 9422191
    Abstract: A method to prepare polymer woven fabric surface with selective oleophilicity or hydrophobicity and oil-oil separation and oil-water separation filter prepared by using the surface. The method to prepare the surface with selective oleophilicity or hydrophobicity includes steps comprising a step to form nano meter sized pores on the surface of the polymer woven fabric surface with micro sized pores through drying type etching; and a step to form selective oleophobic or hydrophobic film on the nano meter sized pores. It is possible to control hydrophobic/oleophobic property according to pore size, material or thickness of the film and this polymer surface with hybrid pores can be used in various areas such as an oil filter for car capable of selective separation of oil-oil mixture and water-oil mixture, disposal of waste oil, treatment of marine oil leakage, and pretreatment of crude oil refinement.
