Embodiment 1

[0040] The preparation of monodisperse poly(styrene-methyl methacrylate-acrylic acid) latex particles with a particle size of 50nm is as follows:

[0041] The monomer mixture methyl methacrylate (1.2 g), styrene (18 g) and acrylic acid (1.2 g), pH buffer (1.0 g) and emulsifier sodium dodecyl sulfonate (0.0786 mg) were dissolved in In water (100 mL), the resulting mixed system was stirred and mixed at 600 rpm, and heated to 75°C. Add 10 ml of potassium persulfate (0.8 g dissolved in 20 ml of water) aqueous solution to start the reaction, add 5 ml of potassium persulfate aqueous solution after 3.5 hours of reaction, and add the remaining potassium persulfate aqueous solution after the reaction continues for 3 hours. The reaction then continued for 2 hours and then ended. Finally, polystyrene-polymethyl methacrylate-polyacrylic acid triblock monodisperse polymer latex particles (monodisperse poly(styrene-methyl methacrylate-acrylic acid) latex particles) with a particle size of 50 ...

Abstract

The invention belongs to the colloid photonic crystal preparation and application technical field, in particular to a method for preparation of high quality extensive patterning colloid photonic crystal by ink-jet printing. Under room temperature and by effective control of the substrate wetting quality and the surface tension of monodisperse emulsion particle emulsion ink for ink-jet printing, two or more types of monodisperse emulsion particle emulsion with the same particle diameter are respectively put into different ink boxes of an ink-jet printer and the concentration of the monodisperse emulsion particles in the emulsion in each ink box is 0.5-20 wt percent; and after monodisperse emulsion particle emulsion ink is used for the ink-jet printer to print patterns and then dried, a high-quality colloid photonic crystal with photon ban gaps in the ultraviolet light region and the visible light region is formed on the substrate surface. The highly-sequentially assembled colloid photonic crystals prepare by the invention has good optical property, realizes control effect of photon ban gaps to light and has wider application prospect in the fields of optical devices and optical integrated circuits.

Description

Technical field [0001] The invention belongs to the technical field of preparation and application of colloidal photonic crystals, and particularly relates to a method for preparing high-quality large-area patterned colloidal photonic crystals through an inkjet printing method. Background technique [0002] Because patterned photonic crystals have broad application prospects in the fields of optical devices, displays, and microfluidics, the preparation of patterned photonic crystals has aroused great interest of researchers. The preparation of patterned photonic crystals is generally obtained by using laser direct writing or template assembly. Laser direct writing requires a special high-cost direct writing device. Although the template assembly method is simple, the resulting pattern is limited by the template, and The template preparation process is also very complicated. It should be a simple and easy method to directly prepare patterned photonic crystals by inkjet printing. ...
