Abstract

The invention relates to a triazine ring covalent organic polymer and an electrode material, as well as a preparation method and application thereof. The preparation method of the triazine ring covalent organic polymer comprises the following steps: S1, mixing nitrile monomer and zinc chloride, reacting for 40-80 hours under a zinc chloride molten state to obtain black solid, wherein the molar ratio of the nitrile monomer to the zinc chloride is 1:(1-15); and S2, dissolving, filtering and drying the black solid obtained in the S1 to obtain the triazine ring covalent organic polymer. The preparation method is simple in process and low in cost, is easily for large-scale production, and has a great application space in the field of membrane capacitance deionizing and desalting. The triazine ring covalent organic polymer has excellent electro-adsorption performance due to nitrogen-doped heteroatom effect and microporous effect, has excellent hydrophily, chemical stability, thermal stability and electron conducting efficiency; and double electrode layers are generated in the adsorbing process, and a great amount of charged particles are adsorbed.

Description

technical field [0001] The invention belongs to the field of capacitive deionization electrode materials, and in particular relates to a triazine ring covalent organic polymer, an electrode material and a preparation method and application thereof. Background technique [0002] As a new water treatment technology, membrane capacitive deionization technology, compared with traditional water treatment technologies such as reverse osmosis, electrodialysis, distillation, etc., has attracted more and more attention because of its simplicity, safety, low energy consumption and no secondary pollution. more attention. By applying a DC voltage, the charged particles in the fluid are adsorbed to the oppositely charged electrode material under the action of the electric field force, and an electric double layer is formed on the electrode surface, and the electrode surface is covered with an anion and cation exchange resin film to effectively reduce common ions The interference of deso...
