A method is provided for coating or filling a porous material. According to one embodiment, the method includes providing the porous material, delivering precursor molecules by gas phase exposure into pores of the porous material, and reacting the precursor molecules to form a polymer inside the pores.

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.

A population of nanocomposite particles including nanoparticles and poly (ethylene imine) (PEI) grafted thereto. In some embodiments there is no intervening layer between the nanoparticles and the PEI. Methods of making and using nanocomposite particles are also disclosed.

The present invention relates to a method for preparing a porous polymer film having a controlled pore depth, and a porous polymer film prepared thereby. A method for preparing a porous polymer film according to the present invention allows the pore depth of a porous film to be controlled simply and at a low cost, and thus allows adjustment of the light reflectance of the prepared film. A large-area film can be prepared by means of a simple method and thus can be applied to various industry fields. Films having different reflectance can be prepared and thus can be applied as low-reflection and high-reflection films for solar cells, and also as a low-reflection or high-reflection thin polymer film in the construction field or material and equipment field.

A silicone coating film provided as a surface layer of an irradiated object exposed to ultraviolet irradiation, includes a silicone rubber as a base material and titanium oxide particles with an average particle size of less than 100 nm. A laminated structure includes a first layer including a silicone rubber as a base material, and a second layer laminated on the first layer, wherein the second layer is the silicone coating film.
