Embodiment 1

[0021] A kind of preparation method of the photochromic carbon fiber based on inorganic material of the present invention, described method comprises the following steps:

[0022] (1) Preparation of dispersant: 0.1 mol of sodium methacrylate and 0.03 mol of allyl polyoxyethylene ether monomer with a degree of polymerization of 23 were simultaneously dissolved in 200 mL of deionized water to prepare a monomer solution for later use; Then, under stirring conditions, the temperature is controlled at 79-81°C, and the configured monomer and 50mL ammonium persulfate initiator aqueous solution are respectively added dropwise to a four-necked flask filled with 100mL deionized water, wherein the ammonium persulfate The mass accounts for 0.3% of the total mass of the monomer, and the dropping time is controlled at 2.5h. After the dropping is completed, it is kept warm for 3.5h; finally cooled to obtain the dispersant; the weight average weight of the dispersant is measured by gel permeat...

[0027] A kind of preparation method of the photochromic carbon fiber based on inorganic material of the present invention, described method comprises the following steps:

[0028] (1) Preparation of dispersant: a certain quality of sodium methacrylate and allyl polyoxyethylene ether monomer with a degree of polymerization of 23 were simultaneously dissolved in 200 mL of deionized water to prepare a monomer solution for subsequent use. , the molar ratio of sodium methacrylate to allyl polyoxyethylene ether is 1:0.2; then, under stirring conditions, the temperature is controlled at 79-81°C, and the configured monomer and 50mL ammonium persulfate initiator The aqueous solution was added dropwise to four-necked flasks equipped with 100mL deionized water, wherein the mass of ammonium persulfate accounted for 0.1% of the total mass of the monomer, and the dropping time was controlled at 2h. After the dropping was completed, the temperature was kept for 3h; , that is, a dispersant is...

Embodiment 3

[0033] A kind of preparation method of the photochromic carbon fiber based on inorganic material of the present invention, described method comprises the following steps:

[0034] (1) Preparation of dispersant: Dissolve a certain quality of sodium methacrylate and allyl polyoxyethylene ether monomer with a degree of polymerization of 23 in 200 mL of deionized water at the same time to prepare a monomer solution for later use. Among them, The molar ratio of sodium methacrylic sulfonate to allyl polyoxyethylene ether is 1:0.4; then, under stirring conditions, the temperature is controlled at 79-81°C, and the prepared monomer is mixed with 50mL of ammonium persulfate initiator aqueous solution Add dropwise to four-necked flasks equipped with 100mL deionized water, wherein the quality of ammonium persulfate accounts for 0.4% of the total mass of the monomer, and the dropping time is controlled at 3h. After the dropping is completed, keep warm for 4h; finally cool, That is, the dis...

Abstract

The invention relates to photochromic carbon fibers based on inorganic materials and a preparation method thereof, which are characterized in that tungsten trioxide and molybdenum trioxide are made into a nanoscale oxide aqueous dispersion, a polyacrylate/tungsten trioxide/molybdenum trioxide aqueous dispersion composite emulsion is prepared by performing polymerization and emulsification on the nanoscale oxide aqueous dispersion and a vinyl monomer, and then the emulsion is applied to the surface of carbon fibers to obtain the photochromic carbon fibers based on the inorganic materials. The photochromic carbon fibers prepared by the invention turn from light yellow to blue under the irradiation of a 500W xenon lamp as a light source; after being washed 20 times, the carbon fibers keep photochromism unimpaired. The whole preparation process is simple, and causes no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of carbon fibers, and in particular relates to a photochromic carbon fiber based on inorganic materials and a preparation method thereof. Background technique [0002] Photochromic fiber fabrics mean that their color can change under the irradiation of ultraviolet light or visible light. Because photochromic fiber fabrics have the advantage of being able to change colors, they are widely used in many fields, such as: military camouflage, magic shows, etc. In addition, with the improvement of people's living standards, people's desire for novelty in textiles is increasing, and the function of clothing has changed from the original warmth-keeping type to the hedonic type. Photochromic clothing just satisfies this consumer psychology. Therefore, photochromic fiber fabrics have become the focus of current fiber modification. [0003] Carbon fiber is a new type of fiber, which has many advantages that other fib...
