This invention relates to a dendrite-free zinc electrode for electrochemically mediated amine regeneration, its preparation method, and its application. The invention modifies an electrolyte containing diethylenetriamine, zinc chloride, and potassium chloride using electrolyte additives with carboxyl functional groups (such as sodium maleate, thiosalicylic acid, and ammonium formate). These carboxyl functional groups selectively adsorb onto the zinc electrode surface, enhancing the binding ability of zinc ions to the low surface energy (002) crystal plane of zinc. This guides zinc ions to preferentially deposit along the (002) crystal plane, constructing a flat and dense zinc deposition layer, ultimately effectively inhibiting zinc dendrite growth. A dendrite-free zinc electrode with a high proportion of preferentially oriented Zn (002) crystal planes is prepared by constant current electrodeposition in an electrolyte containing diethylenetriamine, zinc chloride, and potassium chloride. The prepared electrode surface is dense and flat, dendrite-free, with a significantly improved relative texture coefficient of the Zn (002) crystal plane, reduced CO2 desorption energy consumption, and improved corrosion resistance and hydrogen evolution inhibition capabilities. The present invention features a simple process, mild conditions, and low cost, and is suitable for electrochemically mediated amine regeneration carbon capture systems.

The invention belongs to the technical field of thermoplastic molds. The invention provides a low-temperature thermoplastic film and a production method thereof, and the method comprises the following steps: S1, uniformly mixing 100 parts by weight of polyvinyl chloride resin, 11.7-12.2 parts by weight of di-n-octyl phthalate, 3.5-4 parts by weight of epoxy triglyceride, 8.5-9 parts by weight of a stabilizer, 1.2-1.5 parts by weight of thiosalicylic acid modified chlorinated paraffin and 1.5-1.8 parts by weight of ethylene bis stearamide to obtain a mixture; s2, putting the mixture obtained in the step S1 into a double-screw extruder, and extruding and granulating to obtain a granular material; and S3, putting the granules obtained in S2 into an injection molding machine, and carrying out injection molding to obtain the low-temperature thermoplastic film. The addition amount of the epoxy triglyceride is increased, so that the softening temperature of the prepared low-temperature thermoplastic film is reduced, and the tensile strength of the low-temperature thermoplastic film is further improved.
