[0031] In this embodiment, reactive dyes are used to dye pure cotton fabric, and carbonized pure cotton fabric electrodes are prepared by carbonization process.

[0032] (1) Put 1 g of pure cotton fabric in a sodium hydroxide solution with a concentration of 15 g / L, shake it at a constant temperature at 95 °C for 1 h, wash it with deionized water until it is neutral, and dry it at 60 °C until it reaches a constant weight.

[0033] (2) Add the fabric in step (1) to 10% (o.w.f.) dye liquor (referring to the weight of the dye relative to the fabric is o.w.f.), the bath ratio is 1:50, add salt after dyeing at 60°C for 15 minutes , continue dyeing at 60°C for 15 minutes, then heat up to 90°C at a rate of 2°C / min, add soda ash, fix the color at 90°C for 30 minutes, cool down after dyeing, take out the sample, wash with cold water and soap (soap flakes) 2g / L, soda ash 2g / L, 95°C, 10min, liquor ratio 1:30), washing with water, and drying.

[0034] (3) Clean the fabric in step (2) wit...

Embodiment 2

[0044] In this example, acid dyes are used to dye silk fabrics, and carbonized silk fabric electrodes are prepared by carbonization process.

[0045](1) Add 1g of silk fabric to the dye solution of Weak Acid Red 2% (o.w.f.), Ammonium Sulfate 10% (o.w.f.), Sodium Sulfate 10% (o.w.f.), the bath ratio is 1:100, make up the required amount according to the bath ratio Water volume, after the dyeing bath is configured, squeeze the silk fabric soaked in water and put it into the dyeing bath to start dyeing. Under the condition of constant stirring, dye at 60°C, and then gradually heat up to 2°C / min. 90°C, keep warm and dye for 60 minutes, take out the sample after dyeing, wash with cold water, wash with water, and dry.

Abstract

The invention relates to a heteroatom-doped flexible fabric-based carbon electrode material and a preparation method and an application thereof. The electrode material is a three-dimensional network-structured flexible self-supporting carbon electrode material. The preparation method comprises the steps of immersing fabric into an alkali solution and performing oscillating, washing, drying until reaching a constant weight to obtain processed fabric; and immersing the processed fabric into a dye liquor to be dyed, then performing washing, drying in the air, then carbonizing, and cooling to the room temperature to obtain the carbon electrode material. According to the preparation method, the conventional dyeing process is combined with the preparation of a supercapacitor carbon electrode; hetero atoms are introduced to the fabric-based carbon material through a simple and practicable method; in addition, the used raw materials are rich and low in cost; and the prepared electrode material has flexible three-dimensional conductive network structure and excellent electrochemical performance, and has high application prospect in the fields of portable electronic products and intelligent fabrics.

Description

technical field [0001] The invention belongs to the field of electrode materials and their preparation and application, in particular to a heteroatom-doped flexible fabric-based carbon electrode material and its preparation and application. Background technique [0002] With the development of our country's economy and the growth of population, the consumption of energy is increasing day by day, and the traditional non-renewable energy resources such as coal and oil are becoming increasingly exhausted. Environmental and energy issues are becoming increasingly prominent. Therefore, it is of great significance to seek renewable clean energy to reduce environmental pollution and promote the sustainable development of human beings. [0003] Supercapacitors, as a new type of electrical energy storage device, have attracted widespread attention from society due to their high energy density, long cycle life, and good stability. Carbon materials are widely used as an electric doub...
