Problems solved by technology

However, organometallic complexes (Alq 3 , Znq 2 etc.) are susceptible to environmental factors such as oxygen, pH, light, humidity and temperature, etc., resulting in oxidation and deterioration
These environmental factors limit the application of organometallic complexes in textiles, smart glass, smart agricultural films and other civilian fields

Abstract

The invention provides a photoluminescence organometallic complex microcapsule and a preparation method thereof, and belongs to the technical field of polymer composite material synthesis. The preparation method thereof comprises the following steps: (1) preparing an internal water phase, (2) preparing an oil phase, (3) adding the internal water phase prepared in the step (1) into the oil phase prepared in the step (2) at one time, and heating to obtain a water-in-oil type primary emulsion, (4) preparing an external water phase, (5) dropwise adding the water-in-oil type primary emulsion prepared in the step (3) into the external water phase and stirring in 20-80 DEG C; and carrying out post-treatment to obtain the photoluminescence organometallic complex microcapsule. The preparation method thereof provided by the invention is simple to operate, the weather resistance of the prepared photoluminescence organometallic complex microcapsule is enhanced, and the compatibility of the photoluminescence organometallic complex and a coating is improved; and the industrial application range of the photoluminescence organic metal complex is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of synthesis of polymer composite materials, and in particular relates to a photoluminescent organometallic complex microcapsule polymer composite material and a preparation method thereof. Background technique [0002] Photoluminescent materials have the characteristics of sensitive discoloration, bright colors, environmental friendliness, low price, and simple preparation. They have broad application prospects in the fields of photoelectric memory and switching devices, organic field-effect transistor devices, organic semiconductor light-emitting devices, and organic solar cells. . [0003] There are many types of photoluminescent materials, which can be roughly divided into two types: high polymers and oligomers. Compared with high polymers, oligomers have the advantages of easy purification, easy film formation, and easy modification, and are widely used in organic optoelectronic devices. Oligomers are...
