Abstract:
The present invention relates to a structure for oil collection, a method for producing the same and, in particular, to a structure for oil collection. In the structure of the present invention, a hydrophilic polymer layer is coated on the surface of a reticulated type supporter and water resistance intensifier is coated on the surface of the hydrophilic polymer layer. The structure for oil collection according to the present invention can allow water to pass but separate oil to take away, collecting oil existing on the surface of water without secondary contamination. The hydrophilic polymer formed on the structure surface is cross-linked to easily remove the hydrophilic polymer by water, leading to prolonged life time of the structure of the present invention.
Abstract:
The present invention relates to a manufacturing method of polymer gel filter media using radiation and polymer gel filter media manufactured thereby, which is able to easily fill a filter regardless of shape of the filter, to fractionally filter various sizes of particles in a solution at once, and to remove filtration residues in drying due to the volume expansion and contraction characteristic, and, therefore, has the effect capable of being reused semi-permanently.

Abstract:
PURPOSE: A pharmaceutical composition and a hydrogel containing an Impatiens balsamina extract, metronidazole, and a biocompatible polymer are provided to suppress athletes foot, and to treat ulcer, wound, or burn. CONSTITUTION: A pharmaceutical composition for preventing or treating athletes foot contains an Impatiens balsamina extract, metronidazole, and a biocompatible polymer. The Impatiens balsamina extract is prepared by mixing each extract of Impatiens balsamina flowers, leaves, and stems. A hydrogel for preventing or treating athletes foot is prepared by crosslinking a mixture of an Impatiens balsamina extract, metronidazole, a biocompatible polymer, and purified water by radiation. A method for preparing the hydrogel comprises: a step of preparing a Impatiens balsamina extract mixture; a step of dissolving the extract mixture, the biocompatible polymer, and metronidazole in purified water and preparing a mixture solution; a step of pouring the mixture solution on a frame and molding in a gel type sheet; and a step of irradiating the sheet by radiation.
