Problems solved by technology

Most of the above documents use dipping and spraying methods to prepare MXene-based fibers / fabrics / fabrics / textiles. There is no effective combination between MXene and fibers / fabrics / fabrics / textiles. During daily washing or use, MXene will continue to fall off, making MXene-based fibers / fabrics / fabrics / textiles are becoming less and less functional

Embodiment 1

[0015] Use a plastic measuring cylinder to weigh 40mL of hydrofluoric acid with a concentration of 50%, slowly pour it into a polytetrafluoroethylene beaker, and put 2g of 200 mesh titanium aluminum carbide (Ti 3 AlC 2 ) The MAX phase ceramic material was slowly added into the beaker, stirred magnetically at room temperature for 24 hours at a speed of 200 rpm, centrifuged the reacted solution at 4000 rpm, and poured the upper cloudy liquid into the waste liquid bucket. Then use deoxygenated water to repeatedly sonicate, centrifuge and wash until the pH value of the liquid is 6. Finally, the precipitate was dried under vacuum at room temperature to prepare Ti 3 C 2 T x Two-dimensional nanosheet powder, spare.

[0016] Prepare dopamine Tris-HCl buffer solution with a mass fraction of 10%, adjust the pH value to 8.5, and Ti 3 C 2 T x The two-dimensional nanosheet powder was dispersed in dopamine Tris-HCl buffer and reacted for 24 hours. After taking it out, it was washed r...

Embodiment 2

[0023] Ti 2 CT x Refer to Example 1 for the preparation method of the two-dimensional nanosheet powder.

[0024] Prepare dopamine Tris-HCl buffer solution with a mass fraction of 10%, adjust the pH value to 8.5, and Ti 2 CT x The two-dimensional nanosheet powder was dispersed in dopamine Tris-HCl buffer and reacted for 24 hours. After taking it out, it was washed repeatedly with ethanol, centrifuged, and dried in vacuum to obtain aminated Ti 2 CT x Two-dimensional nanosheet powder.

[0025] Mix 1g of electric spinning silk fabric with 15g of thionyl chloride, then slowly add 1.5g of DMF, reflux at 80°C for 12h, take it out, wash it repeatedly, and dry it in low-temperature vacuum to prepare acyl chloride silk fabric.

[0026] 0.25g aminated Ti 2 CT x The two-dimensional nanosheet powder was dispersed in 50mL deionized water to prepare 5g / L aminated Ti 2 CT x Two-dimensional nanosheet dispersion, followed by 1000w power ultrasonication for 4h, after the ultrasonication...

Abstract

The invention provides a multifunctional real silk fabric based on MXene two-dimensional nanosheets. A preparation method comprises the following steps that (1), the MXene two-dimensional nanosheets are prepared; (2), an aminated MXene two-dimensional nanosheet is prepared; (3), acylating chlorination modification is carried out on the real silk fabric; and (4), the acylating chlorinated real silk fabric is dipped in the aminated MXene two-dimensional nanosheet dispersion liquid to react for a period of time, and finally the multifunctional real silk fabric based on the MXene two-dimensional nanosheets is prepared. The prepared real silk fabric has multiple functions of resisting bacteria, resisting ultraviolet rays, resisting electromagnetic radiation, conducting electricity and the like. Moreover, the MXene two-dimensional nanosheets are firmly attached to the surface of the real silk fabric and do not fall off greatly along with the increase of washing times, so that the additional value of the real silk fabric is greatly increased, and the application range of the real silk fabric is greatly widened.

Description

technical field [0001] The invention relates to the fields of textile fabrics and functional nanomaterials, in particular to a multifunctional silk fabric based on MXene two-dimensional nanosheets. Background technique [0002] Silk is a natural protein fiber with gorgeous and soft luster, delicate and smooth hand feeling, good drapability, good moisture absorption and air permeability, and is known as the "fiber queen" and "the second skin of the human body". In addition, silk is rich in 18 kinds of amino acids needed by the human body, which has the functions of calming the nerves, skin care, regulating metabolism, and enhancing cell vitality. However, silk and its products still have defects such as easy to wrinkle, yellowing, non-wearing, fading, difficult to manage, and poor anti-ultraviolet and antibacterial properties during use. Especially with the prevalence of smart wearable devices, traditional silk products have been difficult to meet people's requirements for s...
