Embodiment Construction

[0027] A high-voltage electric field effect color-changing material, including two parts: a component one inorganic material and a component two organic material, wherein the component one is selected from WO 3 or Co 3 o 4 , the second component is a compound comprising formula 1:

[0028] Formula 1

[0029]

[0030] Among them, R 1 selected from the group consisting of single bond, phenyl, biphenyl, terphenyl, thienyl and bithienyl; wherein, R 2 An alkyl chain of 1 to 3 carbon atoms or H; R 3 is an alkyl chain of 1 to 3 carbon atoms or H.

[0031] A preparation method of a high-voltage electric field effect color-changing material, the steps are as follows:

[0032] Step 1: Add component 2 into anhydrous dichloroethane at room temperature, and then completely dissolve component 2 in anhydrous dichloroethane under the protection of an inert gas with a stirring speed of 200r / s, and mix well, To obtain the mixture, the temperature of the mixture was raised from room te...

Abstract

The invention relates to a high voltage electric field effect color changeable material and a preparation method thereof. The high voltage electric field effect color changeable material comprises two parts, namely an inorganic material component I and an organic material component II; and the changeable material is green when not under the effect of voltage, and is red under the effect of high voltage electric field of more than 1000 V. The electric affected color changeable material prepared by the invention has good electrochemistry oxido-reduction reversibility; and the product made of the electric affected color changeable material has a short response time, with the color change being reversible and highly sensitive, has a certain memory storage function, has good chemical stability, thermal stability and an anti-solution corrosion property.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a high-voltage electric field-induced discoloration material and a preparation method thereof. Background technique [0002] Electrochromism (EC) refers to a reversible discoloration phenomenon in which the material is oxidized or reduced under the action of an external electric field, resulting in a reversible change in light transmission or reflection, which is manifested in color in appearance. Electrochromic materials can generally be divided into two categories: inorganic electrochromic materials and conductive polymer electrochromic materials: inorganic materials are electrochromic materials that have been studied earlier, and have high color contrast, high cycle stability, and attached Strong force and high thermal stability; Compared with inorganic electrochromic materials, conductive polymer electrochromic materials have the advantages of fast re...
