Abstract: A double-inverse opal photonic crystal resin film is formed by embedding nanospheres in pores of polyacrylate inverse opal framework material and then filling the pores of the double-inverse opal photonic crystal resin film with an ethanol solution with hydrophilic acrylamide dissolved therein followed by photopolymerization to form a polyacrylamide network, so as to obtain the double-inverse opal photonic crystal resin film using water as ink. A mass fraction of hydrophilic acrylamide in the ethanol solution is 2 to 8 wt. %. The resin film can induce water to penetrate into the pores of the double-inverse opal photonic crystal resin film, making the nanospheres in the pores of the inverse opal framework distribute from random to order under the action of buoyancy force, thereby eliminating scattering interference and producing brilliant structural colors by regulating refractive index contrast.

Abstract: Disclosed is a method for continuously preparing a water-soluble azo dye by coupling a nebulizer with a pipeline. According to the method, the nebulizer is coupled with a pipeline with an interception tower plate, atomized and mixed reaction liquid flow flows through the pipeline with the interception tower plate, and mixing and reacting are further enhanced through turbulent mixing on the tower plate, so that instant separation of reaction heat generated in an atomizing contact reaction from a reactant is achieved, and normal-temperature rapid continuous production of the water-soluble azo dye is achieved. Fog drops which are atomized by using the nebulizer have small particle diameter and large specific surface area, so that a diazo salt and a coupling component are sprayed separately, move face to face and can be fully contacted, and mixing and reacting speeds are increased. The preparation method is simple, and compared with preparation of a dye of the same kind with a batch reactor, in the reparation process of the water-soluble azo dye, a cold source is not required to be added additionally for cooling, thereby reducing energy consumption and improving production quality and efficiency.

Abstract: A method for preparing a large-area structural chromogenic pattern by ink-jet printing, a structural chromogenic pattern obtained by the method, and an anti-counterfeiting method based on a structural color change. A dispersion liquid containing mono-disperse colloidal microspheres with high index of refraction is printed onto a piece of paper by using an ink-jet printer, and nano-microspheres are arranged and assembled on the paper to obtain a micro-structure having the features of being ordered from a short distance and disordered from a long distance. A pretty structural color can be observed by means of the interaction of the structure with light, thus displaying a pattern, changing the angle of observation, changing the brightness of the structural color, and hiding and displaying the pattern. The method is simple and convenient, is widely applicable, and can achieve the preparation and anti-counterfeiting of a large-area structural color without external stimulation.
