Abstract: A filter medium is provided. A filter medium according to an embodiment of the present invention comprises: a fiber web layer of a three-dimensional network structure including nanofiber; and a hydrophilic coating layer which covers at least a part of the outer surface of the nanofiber. According to this, a flow rate can be remarkably increased due to the improved hydrophilicity of the filter medium. Also, as the improved hydrophilicity is maintained for a long period of time, the lifespan can be remarkably prolonged. Furthermore, since the modification of a porous structure of the filter medium is minimized during the process of hydrophilization so that the initially designed physical properties of the filter medium can be exhibited in its entirety, the filter medium having chemical resistance, excellent water permeability and durability can be variously applied in the water treatment field.

Abstract: Electromagnetic wave shielding material including a conductive fiber web with multiple pores and a heat dissipation unit provided in at least some pores that is so excellent in flexibility, elasticity, and creasing/recovery that it can be changed in shape freely and brought in complete contact with a surface where the material is to be disposed even if the surface has a curved shape, uneven portions, or stepped portions, thus exhibiting excellent electromagnetic wave shielding performance and prevent deterioration thereof despite various shape changes. Since heat dissipation performance is excellent, heat generated in an electromagnetic wave source can be rapidly conducted and released. Even if parts are provided in a narrow area at high density, the material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. The invention is employed for light, thin, short, and small or flexible devices.

Abstract: A filter medium is provided. The filter medium according to an embodiment of the present invention comprises a second support body and a nanofiber web layer which are sequentially stacked on each of both surfaces of a first support body, and is a filter medium having a flow path through which a filtrate filtrated in the nanofiber web flows in the direction of the first support body, wherein the nanofiber web has a basis weight of 30 g/m2 or less, the first support body has a basis weight of 250 g/m2 or more, and a thickness of 90% or more of the total thickness of the filter media. Accordingly, even in a backwash process performed at high pressure, as the shape, structural deformation, and damage of the filter medium can be minimized, the use period can be extended. In addition, as the flow path is smoothly secured at high pressure applied at the time of filtration and/or backwashing, the filtration water is quickly discharged to the outside from the inside of the filter medium or the backwashing efficiency is very excellent, and accordingly it is possible to be applied in various ways in various water treatment fields.

Abstract: Provided is a flexible electromagnetic wave shielding material. An electromagnetic wave shielding material according to an embodiment of the present invention includes a conductive nanofiber web having a nanofiber web formed of a nanofiber and including multiple pores and a metal layer covering at least a portion of the nanofiber disposed on a surface portion of the nanofiber web, wherein a metal particle is provided in at least some of the pores; and an elastic member brought in contact with one surface of the conductive nanofiber web of the metal layer. Thus, the electromagnetic wave shielding material is so excellent in elasticity that the electromagnetic wave shielding material may be freely changed in shape, and can be attached to and brought in complete contact with a surface where the electromagnetic wave shielding material is intended to be disposed even if the surface has a curved shape such as an uneven portion or a stepped portion, thus exhibiting excellent electromagnetic wave shielding performance. Also, it is possible to prevent deterioration of the electromagnetic wave shielding performance despite various shape changes. Furthermore, even if parts are provided in a narrow area at a high density, the flexible electromagnetic wave shielding material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. Thus, the present invention may be easily employed for a light, thin, short, and small or flexible electronic device.

Abstract: A liquid drug-filtering filter medium is provided, which can include a nanofiber web having a three-dimensional network structure for filtering foreign substances included in a liquid drug. According to the embodiment, the occurrence of differential pressure when drawing in and filtering a liquid drug is minimized, and thus the liquid drug may be quickly drawn into a syringe cylinder within a short time and by applying small force, and at the same time, the filtration rate of foreign substances in the liquid drug is very outstanding. A method for producing the liquid drug-filtering filter medium is also provided, which enables the very easy adjustment of a pore structure of the filter medium or the diameters of the pores in order to enable the pore structure to minimize the occurrence of differential pressure or change the differential pressure to a target level.
