Embodiment 1

[0019] Graphene was placed in a horizontal quartz tube in ammonia and argon (NH 3 : Ar volume ratio = 1:1) in a mixed atmosphere, put it in a furnace and heat it at 800°C for 1 hour, stop heating, keep the mixed air flow, wait for the quartz tube to cool down to room temperature, turn off the ammonia gas, and take the product out of the quartz tube That is, nitrogen-doped graphene is obtained.

[0020] The nitrogen-doped graphene was ultrasonically dispersed in a 5% mass concentration PEO (polyethylene oxide Mw: 2000) aqueous solution to obtain a nitrogen-doped graphene solution. The solution of nitrogen-doped graphene is coated on the surface of cotton cloth by dipping, filling, hydrothermal, printing and self-assembly methods, and then the cotton cloth is dried, dried and cured, cleaned and re-dried and cured to obtain the obtained Describe the cloth 1 of doping type graphene coating.

Embodiment 2

[0022] Put 0.2g of graphite powder in a 50ml polytetrafluoroethylene reaction kettle, add 3ml of chlorosulfonic acid, heat the mixture at 120°C for 5 hours, then take out the sample and put it in a beaker, add 15ml of concentrated sulfuric acid into it, Edge-oxidized graphene can be obtained by adding 6 ml of hydrogen oxide solution dropwise under stirring condition. Dilute 10ml of graphene oxide aqueous solution with a concentration of 4mg / ml with 25ml of deionized water, add a small amount of urea, place the solution in a 50ml polytetrafluoroethylene autoclave, and react at 180°C for 12 hours to obtain the product. Finally, filter and wash with water and dry to obtain nitrogen-doped graphene.

[0023] Nitrogen-doped graphene is placed in NMP (N-methylpyrrolidone) for ultrasonic dispersion to obtain a solution of nitrogen-doped graphene. The solution of nitrogen-doped graphene is coated on the surface of chemical fiber cloth by dipping, filling, hydrothermal, printing and co...

Embodiment 3

[0025] Put 3g of graphene into the tube furnace, evacuate the tube furnace, and first feed the Ar-loaded gasified BCl 3 (4:1 v / v) as the reaction gas, the Ar flow rate is controlled to 250ml / min, and the temperature in the tube furnace is raised to 800°C at a heating rate of 30°C / min and kept for 3 hours, and then the Ar load is introduced Gasified pyridine monomer (5:1 v / v) was used as the reaction gas, the Ar flow rate was controlled to 50ml / min, and the temperature was kept for 6 hours. After the tube furnace was cooled to room temperature, B and N double-doped graphene was obtained. .

[0026] The B, N double-doped graphene is placed in water and ultrasonically dispersed to obtain a B, N double-doped graphene solution. The solution of B, N double-doped graphene is coated on the surface of silk cloth by dipping, filling, hydrothermal, printing, self-assembly and coating methods, and then the silk cloth is dried, dried and solidified, cleaned and refurbished. The doped gra...

Abstract

The invention provides a fabric with a doped-type graphene coating. The fabric is characterized in that the surface of the fabric is coated with doped-type graphene, and doped elements are non-metal elements. The fabric provided by the invention has the advantages that the catalytic, adsorbing and conducting characteristics of non-metal doped graphene are utilized, and the surface of the common fabric is coated with one layer of or multilayer non-metal doped graphene, so that the fabric has the characteristics of antisepsis, deodorization and dustproof, antifogging and antistatic effects; non-metal doped graphene of the coating has non-toxic and pollution-free effects and is easy to produce and manufacture; the preparation process is simple, and the fabric product is light and is high in practicability.

Description

technical field [0001] The invention relates to the field of textile cloth, in particular to a doped graphene-coated cloth and a preparation process thereof. Background technique [0002] Graphene is a two-dimensional graphite material with a single molecular layer, and is the only two-dimensional free atomic crystal found so far. Graphene is currently the thinnest but also the hardest nanomaterial in the world. It is almost completely transparent and only absorbs 2.3% of light; its thermal conductivity is as high as 5300W / m·K, which is higher than that of carbon nanotubes and diamonds. The electron mobility exceeds 15000cm2 / V·s, which is higher than carbon nanotubes or silicon crystals, and the resistivity is only about 10-6Ω·cm, which is lower than copper or silver. It is the material with the smallest resistivity in the world. Since its discovery in 2004, graphene has not only received great attention in theoretical science, but also has been widely used in electronics, ...
