Embodiment 1

[0056] The present embodiment discloses a method for preparing a colored inverse opal structure photonic crystal plastic film with bright pearly luster, the details are as follows:

[0057] 1. Preparation of core-shell silica microspheres

[0058] In 100 parts by mass of water, add 4 parts by mass of butyl methacrylate, 3 parts by mass of butyl acrylate, 3 parts by mass of methyl methacrylate, then add 0.002 part by mass of emulsifier sodium dodecylbenzenesulfonate, and 0.09 parts by mass of sodium bicarbonate as a buffer to obtain the reaction solution; keep the reaction solution at 70°C for 1 hour, then add 0.04 parts by mass of potassium persulfate, and react at 70°C for 5h under continuous stirring to prepare poly(methacrylic acid) Butyl ester-methyl methacrylate-butyl acrylate) (P(BMA-MMA-BA)) emulsion, which serves as a template for the preparation of core-shell silica.

[0059] Then measure several milliliters of concentrated ammonia water and vinyltriethoxysilane (VTE...

Embodiment 2

[0071] The present embodiment discloses a method for preparing a colored inverse opal structure photonic crystal plastic film with bright pearly luster, the details are as follows:

[0072] 1. Preparation of core-shell silica microspheres

[0073] Add 10 parts by mass of styrene to 100 parts by mass of water, then add 0.0010 part by mass of emulsifier sodium dodecylbenzenesulfonate to obtain a reaction solution; keep the reaction solution at 70°C for 1 hour, then add 0.04 part by mass of potassium persulfate, The PS emulsion was prepared by reacting at 85 °C for 5 h under continuous stirring conditions, and the emulsion was used as a template for preparing core-shell silica.

[0074] Then measure several milliliters of concentrated ammonia water and vinyltriethoxysilane (VTEO) in a volume ratio of 1:3, accurately measure 20ml of the above-mentioned original solution and add it to the beaker, according to the ratio of 6ml VTEO:80ml deionized water, the total volume is 100ml Th...

Abstract

The invention discloses a colored inverse opal photonic crystal plastic film with a bright pearlescent color and a preparation method and application thereof. Through change of particle sizes of an assembled unit, a plastic film with bright pearlescent red, green and blue colors is obtained. The colored inverse opal photonic crystal plastic film solves the problem that the plastic film colored with pearlescent master batches has non-ideal gloss and poor dispersibility and has a short service life caused by local stress concentration and the traditional polymer inverse opal photonic crystal depends on a solvent for keeping the stable photon crystal structure, has low color saturation and strong dependence on the illumination angle. The colored inverse opal photonic crystal plastic film hasthe advantages of bright pearlescent color, long-lasting color, high color saturation under natural illumination, good fastness and adjustable thermoplasticity. The invention provides a preparation method with simple processes, a low cost and a short period.

Description

technical field [0001] The invention relates to a photonic crystal and a colored plastic film and a preparation method thereof. More specifically, it relates to a color inverse opal structure photonic crystal plastic film, its preparation method and application. Background technique [0002] In the 21st century, the application scope of polymer materials has been continuously expanded, among which plastic products have become inseparable from human daily life. At the same time, the requirements for plastic products in terms of color are also increasing. Since pearlescent pigments, metallic pigments and other pigments can provide a special luster similar to natural pearls, they can reproduce the luster unique to natural pearls, shells, fish scales, etc. These pigments consist of several metal oxides coated with thin layers of mica. When light irradiates the flat interface of pearlescent pigments, reflected light and refraction-reflected light will be generated, and they wi...
