Process for producing articles having an electrically conductive coating
The present invention relates to a process for producing articles having on at least part of their surface an electrically conductive coating by at least partly coating a substrate with a composition comprising finely divided electrically conductive metal particles and a binder and subjecting the coated substrate to at least one treatment with water in the presence of a halide ion source at a temperature in the range from ambient temperature to 200 C. The process of the invention allows articles having an electrically conductive coating to be produced in a simple, rapid and mild way.
ANISOTROPY REDUCTION IN COATING OF CONDUCTIVE FILMS
Provided herein is a method of forming a conductive film, the method comprising: providing a coating solution having a plurality of conductive nanostructures and a fluid carrier; moving a web in a machine direction; forming a wet film by depositing the coating solution on the moving web, wherein the wet film has a first dimension extending parallel to the machine direction and a second dimension transverse to the machine direction; applying an air flow across the wet film along the second dimension, whereby at least some of the conductive nanostructures in the wet film are reoriented; and allowing the wet film to dry to provide the conductive film.

METHOD FOR FABRICATING A CERAMIC MATERIAL
A method for fabricating a ceramic material includes impregnating a porous structure with a mixture that includes a preceramic polymer and a filler. The filler includes at least one free metal. The preceramic polymer material is then rigidized to form a green body. The green body is then thermally treated to convert the rigidized preceramic polymer material into a ceramic matrix located within pores of the porous structure. The same thermal treatment or a second, further thermal treatment is used to cause the at least one free metal to move to internal porosity defined by the ceramic matrix or pores of the porous structure.

ANTI-ICING FILM USING BROADBAND PLASMONIC METASURFACE IN WHICH ANISOTROPIC GOLD NANORODS AND CELLULOSE NANOCRYSTAL PARTICLES ARE CO-ASSEMBLED
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.
HIGHLY DURABLE SPRING AND METHOD OF COATING THE SAME
A highly durable spring of the present invention includes a single-layer coating film with a thickness of 450 m or less, in which the coating film contains an epoxy resin, a phenolic resin, and zinc. The coating film has high corrosion resistance and chipping resistance even if it is a one thin layer with a thickness of 450 m or less. A method of coating a highly durable spring of the present invention includes an application process in which an epoxy resin-based powder coating material which contains an epoxy resin, a phenolic resin, and zinc and is produced by a melt kneading method is applied to a surface of a spring on which a coating-film is formed and a baking process in which the applied epoxy resin-based powder coating material is baked.
USE OF RESIN OR ANTIFOULING RESIN ON UNDERWATER STRUCTURES FOR EASIER CLEAN UP OF BIO-FOULING THEREON AND/OR TO LIMIT BIO-FOULING THAT OCCURS
A resin applied to underwater structures to enable biofouling growing thereon to be removed therefrom much easier than biofouling growing directly on the underwater structure. Adding antifungal properties to the resin enables the resin to prevent, or limit, the growth of biofouling thereon. The antifungal properties are provided by at least some subset of antifungal agents (e.g., copper) and antimicrobial agents (e.g., silver). The agents are mixed with plastic (e.g., polyethylene), melted, extruded into a solid form and then processed into an antifouling resin where the antifouling agent is embedded and integrated in the resin prior to application. The antifouling resin presents its antifouling properties immediately upon application and does not require gradual degradation to expose the active antifouling agents. The antifouling resin is thermal sprayed onto the underwater structure (an initial layer may be thermal sprayed onto an epoxy layer prior to curing to merge the two layers).
Method for compacting an anticorrosion coating
A method for compacting an anticorrosion coating includes projecting water soluble particles.
