Problems solved by technology

However, there is not yet a very suitable oxidizing agent to polymerize 1,5-diaminoanthraquinone
In addition, poly-1,5-diaminoanthraquinone (PDAA) polymerized by traditional methods is extremely limited in its ion transport due to its dense packing structure.

Embodiment 1

[0028] (1) Preparation of manganese dioxide nanorods by hydrothermal method: take 0.237g of KMnO 4 and 2.5 mg of NaOH were dissolved in 30 ml of deionized water. In addition, take 0.38g of MnSO 4 ·H 2 O was dissolved in 30 ml of deionized water. Then the two solutions were mixed, added to an 80ml hydrothermal kettle, and reacted in an oven at 140°C for 12h. Finally, the obtained product was collected by suction filtration, and dried in an oven at 60° C. for 12 hours to obtain manganese dioxide nanorods.

[0029] (2) 108.5 mg of manganese dioxide nanorods in step (1) were dissolved in 25 ml of a mixed solution of N,N-dimethylacetamide and ethanol containing sulfuric acid (the concentration of sulfuric acid was 1 M). After that, 297.8 mg of 1,5-diaminoanthraquinone was dissolved in 25 ml of N,N-dimethylacetamide and ethanol mixed solution containing sulfuric acid (the concentration of sulfuric acid was 1M). Then the two solutions were mixed and reacted at 25°C for 48h. Whe...

Abstract

The invention relates to a preparation method of poly(1,5-diamino-anthraquinone) nanorods. The preparation method comprises the following steps: preparing manganese dioxide nanorods by a hydrothermalmethod; respectively dissolving the manganese dioxide nanorods and 1,5-diamino-anthraquinone in an acid-containing mixed solution of ethanol and N,N-dimethylacetamide; mixing the obtained manganese dioxide solution and 1,5-diamino-anthraquinone solution; carrying out a polymerization reaction; and performing pumping filtration, washing and drying to obtain the poly(1,5-diamino-anthraquinone) nanorods. The preparation method uses manganese dioxide as an oxidant and a mixed solvent of ethanol and N,N-dimethylacetamide to polymerize 1,5-diamino-anthraquinone, a structure favorable for ion transport is constructed, and the electrochemical performance of the poly(1,5-diamino-anthraquinone) nanorods is improved.

Description

technical field [0001] The invention belongs to the field of preparation of conjugated polymer materials, in particular to a preparation method of poly-1,5-diaminoanthraquinone nanorods. Background technique [0002] With the increasingly severe energy crisis and the deterioration of the global environment, the development of sustainable energy has become a global concern. Although solar energy and wind energy are clean and sustainable, they are difficult to be directly used by people because they are greatly affected by regionality and intermittency. Therefore, it is particularly important to develop efficient energy storage devices to solve this problem. [0003] Supercapacitor is an ideal energy storage device because of its ultra-high power density and energy density, and has become a hot spot in social research. As a new type of conjugated polymer, poly-1,5-diaminoanthraquinone has a wider electrochemical window and higher cycle stability than traditional conjugated c...
