    Abstract: In a gas-barrier aluminum deposition film according to one embodiment of the present invention, a seed coating layer containing functional groups of at least one type selected from among a hydroxyl group (—OH), an amine group (—NH), and a carboxylic acid group (—COOH) is formed on a thermoplastic plastic base film to form a seed molecular layer that enables uniform deposition of aluminum, such as AlOx or AlNx, through chemical reaction, on a surface of the coating layer, with aluminum atoms vaporized at the initial stage of aluminum deposition, thereby inducing uniform deposition of an aluminum layer to be subsequently deposited. Therefore, it is possible to provide a deposited film having superior oxygen and water vapor barrier properties compared to existing aluminum deposition films.

    Abstract: Provided are a monovalent anion selective ion exchange membrane and a method of manufacturing the ion exchange membrane. In regard to the monovalent anion selective ion exchange membrane, a surface portion thereof has a high amount ratio of a cation exchange polymer electrolyte, a central portion thereof has a high amount ratio of an anion exchange polymer electrolyte, and an amount ratio of the anion exchange polymer electrolyte with respect to the cation exchange polymer electrolyte continuously increases in the thickness direction thereof from the surface toward the center. Due to this structure, compared to monovalent anions, polyvalent anions may permeate much less through the exchange membrane. Thus, high selectivity for monovalent anions may be obtained.

    Abstract: Disclosed are a polyethylene microporous film and a method of preparing the same. The polyethylene microporous film, which has a laminated structure comprising B layer/A layer/B layer, prepared by melt-mixing a polyethylene and an aliphatic hydrocarbon solvent together at controlled mixing ratios to separately form an A layer and a B layer having different porosities, and then coextruding the A and B layers, thus exhibiting excellent mechanical properties, such as strength and elongation, and high-temperature stability. Therefore, the polyethylene microporous film is suitable for use in a rechargeable battery separator.
