  • Publication number: 20250136823
    Abstract: Provided are an anti-icing film using a broadband plasmonic metasurface produced by co-self-assembling anisotropic gold nanorods and cellulose nanocrystal, and a method for manufacturing the same. A method for manufacturing an anti-icing film including: (a) preparing an ink for an anti-icing film including a bonded body of the cellulose nanocrystal and the anisotropic gold nanorods and a binary mixed solution; (b) coating a substrate with the prepared ink; and (c) evaporating the binary mixed solution from the coated ink, and an anti-icing film manufactured therefrom may be provided. In addition, provided is an anti-icing film having anti-icing/deicing effect only with light irradiation of a visible light wavelength, by including a substrate; and a film layer including a metasurface on the substrate, wherein the metasurface includes a composite arranged in a certain direction, in which the anisotropic gold nanorods and the cellulose nanocrystal particles are co-assembled.

  • Publication number: 20220306933
    Abstract: The present invention relates to a method for coating a quantum dot using droplet evaporation in a confined system, and may provide a new method capable of easily coating the quantum dots by maximizing the continuous Marangoni effect which occurs through the multi-component droplet evaporation phenomenon in the confined system without separate chemical-physical treatment.
