摘要： A method for subjecting garment accessories to a surface electrolytic treatment provides various metallic colors to metallic garment accessories in a cost effective manner. The method can provide a first metallic color on one side of outer surface of the garment accessory and provide a second metallic color on the other side of the outer surface, by placing one or more metallic garment accessories in an electrolytic solution in a non-contact state with an anode and a cathode for passing electric current through the electrolytic solution, passing electric current through the electrolytic solution and generating a bipolar phenomenon on the garment accessory.

摘要： The present invention discloses preparation of a reflective image component and application method thereof. A reflective image component in the present invention consists of a metallic semi-continuous thin film, a porous alumina film and a high reflective metal substrate. The structure is easy in preparation, low in cost, environmental friendly regarding preparing procedures and suitable for large-scale fabrication, which plays a significant role in developing a next generation of image component; the minimum pixel in the image obtained is able to reach nano level, much smaller than the pixel in most of the self-luminous screens at present; the image also provides the ability of reversible color transformations, which can be applied to information encryption and trademark decoration and the like.
