preparation example Construction

[0027] Concrete preparation method of the present invention comprises:

[0028] Step 1: SnCl with a molar mass of 1:2 4 and Na 2 S is dispersed in [Bpy][BF 4 ] In the ionic liquid, in order to ensure uniform dispersion, the mixture needs to be ultrasonically treated for 5-10 minutes;

[0029] Step 2: Add 3×3cm uniform textiles to the above mixture, and ultrasonically treat it for 30-60 minutes;

[0030] Step 3: washing the above silk textiles with deionized water and absolute ethanol for 4 to 6 times, and drying at 60° C. for 2 to 4 hours to obtain the final product.

[0031] N-butylpyridine tetrafluoroborate ionic liquid of the present invention (abbreviated as [Bpy] [BF 4 ]) with a purity of 0.99, purchased from Shanghai Chengjie Chemical Co., Ltd.

[0032] In order to test the attached SnS prepared by the method of the present invention 2 To study the photodegradation effect of textiles under ultraviolet light irradiation, the photocatalytic degradation test was carri...

Embodiment 1

[0035] Step 1: Add 0.01molSnCl 4 and 0.02molNa 2 S was dispersed in 20 mL of [Bpy][BF with a purity of 0.99 4 ] In the ionic liquid, in order to ensure uniform dispersion, the mixture needs to be ultrasonically treated for 5-10 minutes.

[0036] Step 2: Add 3×3 cm silk textiles evenly dipped in red wine to the above mixture, and ultrasonically treat it for 60 minutes.

[0037] Step 3: washing the above silk textiles with deionized water and absolute ethanol for 4 to 6 times, and drying at 60° C. for 2 to 4 hours to obtain the final product.

[0038] Self-cleaning SnS prepared as above 2 Silk textile SEM such as figure 1 As shown, it can be seen from the figure that the SnS on silk textiles 2 The particles are extremely fine and clear in shape, well separated and evenly attached to the fibers. SnS 2 The particle size of the particles is 4nm-24nm.

[0039] In order to test the attached SnS prepared in this example 2 To study the photodegradation effect of silk textiles ...

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is that the solvent of this embodiment is deionized water.

[0043] The self-cleaning SnS prepared in this example 2 Silk textile SEM such as figure 2 As shown, it can be seen from the figure that when no ionic liquid is used as a solvent, SnS 2 Particle agglomeration is serious.

[0044] In order to test the attached SnS prepared in this example 2 To study the photodegradation effect of silk textiles under ultraviolet light irradiation, the photocatalytic degradation test was carried out. After 30 minutes of ultraviolet irradiation, the colorimetric result was grade 7. show [Bpy][BF 4 ] Ionic liquid is the preparation of SnS 2 The best solvent for silk textiles.

Abstract

The invention relates to a preparation method and application of SnS2-attached textile. The textile has a self-cleaning system; in the self-cleaning system, SnCl4 and Na2S are adopted as raw materials, and an N-butyl pyridine tetrafluoroboric acid ionic liquid is adopted as a solvent; the textile is prepared according to an ultrasonic method; the self-cleaning system is applied to ultraviolet degradation of a red wine dip-dyed textile. During preparation of the self-cleaning system, the ionic liquid being low in volatility, high in stability, low in toxicity and incombustible is adopted as the solvent, so as to achieve the objective of green chemistry. The preparation method provided by the invention is simple and easy to operate; the synthesized self-cleaning textile has a good self-cleaning effect under the ultraviolet condition, thereby having the special functions of ultraviolet resistance and self-cleaning.

Description

technical field [0001] The invention belongs to the field of materials science, in particular to a SnS attached 2 Methods of preparation of textiles and their applications. technical background [0002] Silk is a continuous long fiber formed by the coagulation of the silk liquid secreted by cooked silkworms when they cocoon, also known as natural silk. Its main component is the fibrous protein silk fibroin, and tannin, a special substance contained in red wine that is not found in other wines, is a natural dye that is not easy to fade. The silk fibroin on silk is due to its amino acid The special structure of the silk is easy to form a very stable special form with the tannins on the red wine, making it extremely difficult to remove the red wine stains on the silk. [0003] In addition, cotton and linen textiles are natural plant fibers. Plant fibers include cellulose, hemicellulose, lignin, pectin, gum and some non-cellulose sugars. The tannins in the wine will also form...
