Abstract:
A method to prepare low reflective surface according to an example of the present invention comprises: the first step to prepare materials having pillar structure on the surface; the second step to prepare aluminum surface-materials by treating for the pillar structure to have aluminum surface; and the third step to prepare a low reflective surface with dual protuberance structure by forming nano-flake layer on the pillar surface of the material surface through oxidation of the surface aluminum of the aluminum surface-materials. The method to prepare low reflective surface can provide a low reflective surface structure that can be applied to photovoltaic device surface or various display surface as a surface able to reduce reflection significantly by absorbing wavelengths in the range of visible and infrared ray through internally total reflection with simple, low cost, and ecofriendly process.
Abstract:
Disclosed is a hydrophilic material oil fence having a double-porous mesh. The hydrophilic material oil fence having the double-porous mesh includes a floating body floating on a water surface, and a skirt coupled to an upper portion and a lower portion of the floating body and made of a hydrophilic material through which a hydrophilic fluid selectively passes. A mesh hole size of a partial region of the skirt and a mesh hole size of the other region of the skirt are different.
Abstract:
There are provided a food container having improved oxygen barrier properties and a manufacturing method thereof. The food container includes a container made of a plastic material, a buffer thin layer formed on a surface of the container and having a thickness of 5 to 30 nm, and an oxygen barrier thin layer formed on the buffer thin layer. Accordingly, it is possible to provide a food container and a manufacturing method thereof, which can remarkably improve oxygen barrier properties by depositing, using a plasma method, an oxygen barrier thin layer on a porous plastic container having low surface energy without breaking the oxygen barrier thin layer.
Abstract:
There are provided a food container having a silicon incorporated diamond like carbon (Si-DLC) layer and a method thereof. The food container includes a container made of a plastic material; an intermediate thin layer formed on a surface of the container; and a Si-DLC layer formed on the intermediate thin layer. Accordingly, it is possible to provide porous plastic container having a Si-DLC layer and a manufacturing method thereof, which can implement high oxygen barrier properties and excellent mechanical characteristics by stably depositing a Si-DLC layer on a food container having lower surface energy without breaking the Si-DLC layer.
Abstract:
The present disclosure relates to a filter apparatus for oil-water separation, and according to an embodiment of the present disclosure, when the filter apparatus for oil-water separation is mounted in a mixed fluid storage tank for storing a mixed fluid collected in seas or rivers in the event that an oil spill accident occurs, it is possible to drain off only water in the mixed fluid. In addition, it is possible to increase the storage efficiency of the mixed fluid storage tank by selectively draining and removing only water other than oil and impurities in the mixed fluid stored in the mixed fluid storage tank.
