Abstract: A dual-modal information storage and anti-counterfeiting material, and its preparation method are provided. The dual-modal information storage and anti-counterfeiting material uses cadmium sulfide quantum dots (CdS QDs) as information storage material, and uses the controllable photocorrosion of CdS QDs to achieve dual-modal optical information storage and anti-counterfeiting applications. Firstly, the type of ligands and modification degree of CdS QDs are precisely controlled during the aqueous phase synthesise process, so as to effectively control the photocorrosion phenomenon under UV light irradiation. Subsequently, the CdS QDs are loaded in the hydrogel network, and they are also loaded on the substrates such as cloth and paper by spray coating, dip coating or 3D printing, and the information is stored by digital light patterning. Different from the photochromic function of traditional anti-counterfeiting material, the CdS QDs shows dual-modal patterning characteristics in a wide wavelength range.

Abstract: Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

Abstract: There is provided a multilayer structure comprising a layer (A) containing an ethylene-vinyl alcohol copolymer having an ethylene unit content of 1 mol % or more and less than 20 mol %, a viscosity-average polymerization degree of 200 to 5000, and a saponification degree of 80 to 99.7 mol %, wherein a block character of ethylene units is 0.90 to 0.99; and a layer (B) containing at least one resin selected from the group consisting of a polyolefin resin, a polyester resin and a polyamide resin. Such a multilayer structure has excellent oxygen-gas barrier performance. In addition, an aqueous solution containing the ethylene-vinyl alcohol copolymer exhibits excellent viscosity stability even after long-term storage. Therefore, even after a long period of time from preparation of the aqueous solution, it can be uniformly applied to a substrate and thus, a multilayer structure having excellent oxygen-gas barrier performance can be provided.
