Abstract: The present invention relates to a preparation method of an organic zinc catalyst capable of preparing an organic zinc catalyst having a finer and more uniform particle size and more improved activity during a polymerization process for preparing a poly(alkylene carbonate) resin, and a preparation method of a poly(alkylene carbonate) resin using the organic zinc catalyst. The preparation method of an organic zinc catalyst includes reacting a zinc precursor and a dicarboxylic acid in the presence of a dispersant to form a zinc dicarboxylate-based catalyst, wherein a reaction step is performed under a condition at which the number of moles of the dicarboxylic acid present in a reaction system is larger than that of the zinc precursor throughout the entire reaction step.

Abstract: Provided are a porous structure for forming anti-fingerprint coating capable of providing a self-cleaning function to a surface of a substrate, a method of forming anti-fingerprint coating using the same, an anti-fingerprint coated substrate prepared by the same method, and a product including the same. When the porous structure including a lipolytic enzyme is formed on the surface of the substrate, contaminants decomposed by an enzyme are absorbed into a pore, and thus anti-fingerprint coating may be more effectively performed to remove detectable contamination from a surface of the substrate. As a result, contamination by fingerprints on the surface of a display device, the appearance of an electronic device, or building materials can be effectively reduced.
