摘要： Provided is a ventilation member for a vehicle lamp. The ventilation member includes a nanofiber membrane, a composite adhesive layer stacked on one surface of the nanofiber membrane, and a ventilation structure provided in a central portion of the composite adhesive layer and in contact with the nanofiber membrane. The composite adhesive layer includes an acrylic adhesive layer in contact with the nanofiber membrane and a silicone-based adhesive layer provided on one surface of the acrylic adhesive layer. The acrylic adhesive layer is in contact with the nanofiber membrane, the acrylic adhesive layer is infiltrated into the nanofiber membrane to a depth of 30 μm or more. The ventilation member for a vehicle lamp has a water pressure resistance of 1.0 bar or more.

摘要： Provided is a filter medium. A filter medium according to an embodiment of the present invention comprises: a first porous support body which has been electrostatically treated; and a nanofiber web which is disposed on one surface of the first support body and formed by accumulating nanofibers. Accordingly, excellent air filtering efficiency is obtained even for fine dust of PM 2.5 or below, and furthermore, deterioration in air filtering efficiency may be prevented or minimized even when usage is extended for a long period of time. Therefore, the filter medium and the composite filter according to an embodiment of the present invention can be widely utilized as media of filters for various air filtering devices.

摘要： A battery having an electrode assembly comprising a cathode having a cathode collector coated, partially or entirely, with a cathode active material, an anode having a nano-web layer on both sides of an anode collector coated, partially or entirely, with an anode active material, and a separation membrane interposed between the cathode and the anode; an electrolytic solution; and an exterior material which encapsulates the electrolyte solution and the electrode assembly together. Since the battery has a porous nano-web layer, even if the temperature inside the battery increases to cause shrinkage or melting of the separation membrane, a contact between the cathode and the anode is prevented such that ignition and/or explosion of the battery does not occur, ion exchange is not disturbed such that the battery performance does not deteriorate, and the nano-web layer is not molten or released towards the separation membrane even at high temperatures.
