A method for conferring bacteriostatic or bactericidal properties on a surface of an object, comprising: (a) putting the surface into contact with an aqueous solution comprising an ionene-type polymer functionalised by at least one radically polymerisable function, an organic compound with two radically polymerisable functions, an organic compound with three radically polymerisable functions and a photoinitiator, (b) subjecting the surface coated with the aqueous solution to irradiation by means of which a radical polymerisation is initiated and a grafted three-dimensional polymer network comprising ionene-type polymers is obtained. The aqueous solution and the object thus obtained as well as uses thereof in particular for preparing protective garments, for packaging and/or storing fresh food products but also for purifying or decontaminating a solution or a surface.

A long-range electrochromic fiber for infrared camouflage and preparation method thereof are disclosed. The method includes: coating indium tin oxide dispersion, electrolyte solution, and electrochromic material on the surface of the metal fiber sequentially, and preparing counter electrodes and polymer protective layer on the outside of the electrochromic layer to obtain the long-range electrochromic fiber. The obtained long-range electrochromic fiber can realize the regulation of infrared emissivity, can be continuously prepared for more than 100 meters and has a good application prospect in infrared camouflage, wearable display, etc.

The present disclosure relates to the technical field of batteries, and specifically relates to a polyamine composite material and a preparation method therefor, a slurry, a separator, an electrode sheet, and a lithium-sulfur battery containing the same. The polyamine composite material comprises a carboxylated carbon-based material serving as a substrate and a polyamine serving as an outer surface layer, and the polyamine is uniformly and smoothly coated on the outer side surface and/or the inner pore surface of the carboxylated carbon-based material. The material is rich in amino groups and is uniform and stable, can be used in the lithium-sulfur battery, and can effectively adsorb lithium polysulfide during a long cycle process.

This invention relates to an exfoliation layer composed of a cationic polymer electrolyte or organosilane and negatively charged phyllosilicate sheet-shaped nanoparticles, and to a method of manufacturing the exfoliation layer, including a) negatively charging the surface of a substrate, b) applying a cationic polymer electrolyte or performing a silanization process, and c) negatively charging and applying phyllosilicate. Since the exfoliation layer of the invention has an effect of reducing bonding force due to the sheet-shaped nanoparticles therein, the exfoliation layer enables a flexible display to be temporarily fixed on a supporting substrate upon fabrication of the flexible display and to then be easily separated after the completion of the fabrication thereof.
