Embodiment 1

[0044] Embodiment 1, the synthesis of polymer carbon material

[0045] In a clean and dry reactor, add 100 mL of toluene, 30 mL of tetrahydrofuran, 3.0 g of sodium metal, 6.0 g of hexabromobenzene, and 3.0 g of polyvinyl chloride. After 8 hours of reflux reaction under the protection of argon, stop heating and cool to room temperature. Obtain a black polymer carbon material suspension, then add 20 milliliters of absolute ethanol, stir and react for 2 hours, then filter the crude polymer carbon material product under reduced pressure, wash it with acetone 3 times, water 3 times, and 10% hydrochloric acid 2 times, and then washed with water several times until neutral, and dried in vacuum to obtain a pure polymer carbon material.

Embodiment 2

[0046] Embodiment 2, the synthesis of polymer carbon material

[0047] In a clean and dry reactor, add 100 mL of toluene, 2.0 g of sodium metal, 4.0 g of trichlorotribromobenzene, and 2.0 g of trichloropyridine. After 8 hours of reflux reaction under nitrogen protection, stop heating and cool to room temperature to obtain black Polymer carbon material suspension, then add 50 ml of absolute ethanol, stir and react for 2 hours, then filter the crude polymer carbon material product under reduced pressure, wash it with acetone for 3 times, water for 3 times, and 10% phosphoric acid for 2 times , and then washed with water several times until neutral, and dried in vacuum to obtain a pure polymer carbon material.

Embodiment 3

[0048] Embodiment 3, the synthesis of polymer carbon material

[0049] In a clean and dry reaction kettle, add 10mL xylene, 50mL tetrahydrofuran, 3.0g polychloroprene, 3.0g sodium metal, and 6.0g tribromobenzene. After reflux reaction for 10 hours, stop heating and cool to room temperature to obtain a black polymer Carbon material suspension, then add 30 ml of anhydrous methanol, after stirring for 2 hours, the crude product of polymer carbon material filtered under reduced pressure, then wash 3 times with acetone, wash 3 times with water, wash 2 times with 10% sulfuric acid, and then Wash with water several times until neutral, and dry in vacuum to obtain a pure polymer carbon material.

Abstract

The invention discloses a preparation method for a polymer carbon material, and belongs to the technical field of chemical synthetic carbon materials. The preparation method is as follows: on the basis of taking alkaline metal or alkaline earth metal and polyhalogenated olefin, halogenated polyolefin, polyhalogenated hydrocarbon or a derivative thereof as raw materials, carrying out metal coupling reaction in a body of polyhalogenated olefin, halogenated polyolefin, polyhalogenated hydrocarbon or the derivative thereof or the good solvent under an inert environment; after the reaction, utilizing halogen or a reactive hydrogen compound to remove residual metals; washing by use of an organic solvent, pickling, washing, filtering and drying to obtain the polymer porous carbon material. The preparation method disclosed by the invention has the advantages of being simple in equipment, easy to operate, low in cost, less in byproduct, high in yield, good in adsorption, and the like; the polymer carbon material prepared by the preparation method disclosed by the invention can be used as corrosion-resistant wear-resisting, conductive, capacitive, adsorbent, oil-absorbing and hydrogen-storing materials.

Description

technical field [0001] The invention relates to a preparation method of a polymer carbon material, which belongs to the technical field of chemical synthesis of carbon materials. Background technique [0002] With the increasing scarcity of petroleum resources and the continuous deterioration of the ecological environment, the search and development of new energy sources has attracted worldwide attention. Hydrogen energy is recognized as an ideal energy source for human beings in the future for the following reasons: (1) The product of hydrogen combustion and energy release is water, which is clean energy; (2) Hydrogen can be decomposed by natural energy such as solar energy and wind energy. Regeneration; it is a renewable energy source; (3) Hydrogen energy has a high calorific value, and the combustion of hydrogen can produce 1.25×10 6 kJ / kg heat, which is equivalent to the heat generated by the complete combustion of 3kg gasoline or 4.5kg coke; (4) Hydrogen resources are ...
