Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] Such as Figure 1-Figure 6 Shown, based on the color inkjet printing method of polystyrene microsphere array structure, described method comprises:

[0026] White PS beads (polystyrene microspheres) powders of different particle sizes are dissolved in absolute ethanol to prepare a variety of suspensions with a certain concentration and containing beads of different particle sizes, and divide different areas on the substrate to be printed According to the color requirements, different suspensions are sprayed to each area through the nozzle; after the solution is spread and evaporated, a film array composed of small balls of different particle sizes can be obtained on the surface of the substrate;

[0027] At this time, another nozzle is use...

Abstract

The invention discloses a color ink-jet printing method based on a polystyrene microsphere array structure. The color ink-jet printing method comprises the following steps: utilizing white PS microsphere powder with different particle sizes for preparing suspension liquid with various concentrations and containing microspheres with different particle sizes; dividing a substrate needing to be printed into different areas, and spraying different suspensions to all the areas according to color requirements; after the suspension liquid is evaporated, forming a film array formed by small balls with different particle sizes in each area; and spraying gold nano powder with different thicknesses to all the areas according to color requirements, and due to the fact that the gold powder with different thicknesses in the gaps of the thin film array and the small balls forms different colors, achieving color printing. The method is based on a structural color film formed by PS small balls, and gold nano powder with different thicknesses is sprayed in small ball gaps in a uniformly divided small ball array; color change is realized by using an ordered array formed by polystyrene microspheres and local surface plasmon polariton resonance characteristics of gold nanoparticles, namely a spectral absorption effect on an ultraviolet visible region.

Description

technical field [0001] The invention relates to a color inkjet printing method based on a polystyrene microsphere array structure and belongs to the technical field. Background technique [0002] Polystyrene microspheres, or PS beads, are a common polymer microsphere material. The preparation method of polystyrene microspheres with narrow particle size distribution was first reported by Vanderhoff and Brodford in 1955, and then the preparation of polymer microspheres and Research has become a new field of polymer science research. Polystyrene microspheres have the general properties of polymer microsphere materials, such as small particle size, large specific surface area, strong adsorption, good dispersibility, and easy modification and modification. Widely used in biochemistry, electrochemical detection, catalysts, adsorbents, chromatographic packing, coatings and other fields. The reason why noble metal nanoparticles show bright colors is that these nanoparticles have a...
