Abstract: Disclosed are an electrolyte membrane of a membrane-electrode assembly including an electronic insulation layer, which greatly improves the durability of the electrolyte membrane, and a method of preparing the same. The electrolyte membrane includes an ion exchange layer and an electronic insulation layer provided on the ion exchange layer, and the electronic insulation layer includes one or more catalyst complexes, and a second ionomer Particularly, each of the one or more catalyst complex includes a catalyst particle and a first ionomer coated on the entirety or a portion of the surface of the catalyst particle, and the one or more catalyst complexes are dispersed the second ionomer.

Abstract: Provided are an artificial leather and a method of manufacturing the same. The artificial leather includes: a base fabric; a polyvinyl chloride film bonded to a surface of the base fabric; bonding layer formed on a surface of the film; a first foam layer formed on the bonding layer in a patterned shape; a first color layer formed on a surface of the foam layer and having the same pattern as the first foam layer; and a surface treatment layer formed on a surface of the first color layer with the same pattern as the first color layer or formed on a surface of the bonding layer without the first foam layer and the surface of the first color layer. to the artificial leather of the present invention may have a light weight and implement various three-dimensional patterns and colors as compared with a conventional PVC foam artificial leather.

Abstract: The present disclosure relates to a skin layer for artificial leather and a method manufacturing the artificial leather, and more particularly, to a composition of an inorganic pigment included in a skin layer. The skin layer for artificial leather, which is the present disclosure, may include a PVC resin, a plasticizer at 84 to 90 phr, and an inorganic pigment at 0.3 phr or more, and a method for manufacturing artificial leather includes: kneading a composition for forming a skin layer, and then forming a skin layer; laminating fiber fabric and the skin layer at a temperature of 150 to 180° C.; and subjecting the laminated fiber fabric and skin layer to roll compression, in which the composition for forming the skin layer may include a PVC resin, a plasticizer at 84 to 90 phr, and an inorganic pigment at 0.3 phr or more.

Abstract: A method is provided for removing a volatile organic compound (VOC) contained in an artificial leather fabric and odor caused by the volatile organic compound by coating the artificial leather fabric with an adsorbent which reacts with a noxious substance containing the volatile organic compound (VOC); and immersing; washing; and drying the reacted artificial leather fabric. The method includes coating the adsorbent and immobilizing the volatile organic compound through a reaction, to prevent volatilization of the organic compound or reduce an amount thereof. Further, after the reaction between the artificial leather fabric and the adsorbent, the artificial leather fabric is washed, to remove the volatile organic compound immobilized on a surface of the fabric from the artificial leather.
