specific Embodiment approach 1

[0018] Specific embodiment one: the preparation method of molybdenum compound suspension with photochromic performance in this embodiment is realized according to the following steps:

[0019] 1. Mix ethanol or acetone with distilled water to prepare a mixed solution;

[0020] 2. The natural hexagonal MoS 2 Block powder is mixed with the mixed solution prepared in step 1 to obtain MoS-containing 2 the mixture;

[0021] 3. Use a high-speed shear emulsifier to process the MoS-containing mixture obtained in step 2 2 The mixed solution is subjected to high-speed shearing treatment to obtain the mixed solution after the shearing treatment;

[0022] 4. Carry out ultrasonic treatment in a water bath to the mixed solution after the shearing treatment to obtain the dispersed mixed solution;

[0023] 5. Centrifuge the dispersed mixed solution obtained in step 4 for 20 to 60 minutes at a speed of 2000r / min to 7000r / min, and take the supernatant after centrifugation to obtain a molybd...

specific Embodiment approach 2

[0026] Embodiment 2: This embodiment differs from Embodiment 1 in that the volume fraction of ethanol or acetone in the mixed solution in Step 1 is 10% to 90%. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0027] Embodiment 3: This embodiment is different from Embodiment 2 in that the volume fraction of ethanol or acetone in the mixed solution in step 1 is 30%-70%. Other steps and parameters are the same as in the second embodiment.

Abstract

Disclosed is a preparation method of a molybdenum compound suspension with photochromic properties. The preparation method of the molybdenum compound suspension with the photochromic properties solves the problem that existing preparation methods of the molybdenum compound suspension with the photochromic properties are complex in process, prone to producing needless by-products and insensitive in the photochromic properties. The preparation method comprises, firstly, mixing ethanol or acetone with distilled water to obtain a mixed solution; secondly, mixing MoS2 blocky powder with the mixed solution to obtain a mixed liquor containing MoS2; thirdly, performing high-speed shearing on the mixed liquor through a high-speed shearing and emulsifying machine; fourthly, performing water bath ultrasonic treatment on the sheared mixed liquor; fifthly, performing centrifugal treatment and taking upper-layer clear liquor to obtain the molybdenum compound suspension. The preparation method of the molybdenum compound suspension with the photochromic properties is simple in process and easy to operate; the obtained molybdenum compound suspension is uniform and stable in quality and can obtain obvious photochromism under ultraviolet radiation for an hour, thereby being sensitive in the photochromic properties.

Description

technical field [0001] The invention relates to a preparation method of a suspension with photochromic performance. Background technique [0002] Materials with photochromic properties can change color when excited by a light source. Because of the performance characteristics of photochromism, photochromic materials occupy an important position in the research and application of functional materials. Photochromic materials are mainly divided into inorganic photochromic materials and organic photochromic materials. Inorganic photochromic materials mainly include the following categories: transition metal oxides, such as WO 3 、MoO 3 、TiO 2 ; Metal halides, such as AgI; Rare earth complexes, metal oxo salts, metal azides, etc. Inorganic photochromic materials have excellent optical, electrical, and magnetic properties, high thermal stability, and fatigue resistance. Among them, transition metal compounds with photochromic properties have become the most promising photochr...
