Description
Technical field
The invention belongs to schemochrome technical field of material is and in particular to a kind of low angle dependence redness zinc sulphide is tied
Structure color colorant and preparation method thereof.
Background technology
The materials arranged in alternating of high low-refraction forms periodic structure-photonic crystal, thus the light of specific wavelength is not
The photon band gap that can be produced by it, thus create schemochrome.Schemochrome is a kind of physics colour generation, has bright-colored, forever
The advantages of colour-fast, environmental friendliness, short preparation period.Passed through the orderly self-assembly method of colloid micro ball in the last few years, and can be formed
Photonic crystal of opals structure, last light have periodic structure photon crystal surface formed by dry penetrate, diffraction, dissipate
The effect of penetrating etc., thus producing bright and colourful schemochrome, but is because with rainbow effect, the color that is, different directions are observed
Difference, thus greatly limit schemochrome in FPD, the application of the aspect such as printed medium and optical device.Generally, make
Standby photonic crystal powder state typically presents white.By after being assembled into orderly photon crystal film could be in only
Reveal schemochrome (cn103288491a, cn103288492a).Also there is researcher to propose the micro black pigment of interpolation can improve
Color saturation, and can effectively reduce the dependence to angle for the schemochrome, reach and protect with viewing angle change schemochrome
Hold constant effect (cn103173039a, 102702791a, 103788770a), but said method is disadvantageous in that, light
In sub- crystal structure color film preparation, need for powder to mix masking with micro carbon black or black pigment, technique is more complicated, and
Opal structural is very high to film coating environment requirement, and big by external environmental interference, the environmental fluctuating of very little all can be to the quality of film
Have a great impact, be therefore difficult to be widely used.Many researchers add in silica or polystyrene colloidal liquid solution
Micro carbon black or melanin, prepare shortrange order, the schemochrome film of longrange disorder, wherein charcoal using methods such as spin coatings
Black or melanic effect is can there is stronger absorption in visible light wave range, thus reduce incoherent scattering so that
Schemochrome film also can show higher color saturation in the state of shortrange order, longrange disorder, simultaneously this short
Cheng Youxu, the structure of longrange disorder, because isotropism, has low angle dependence, that is, with the change of viewing angle,
Color is basically unchanged, and can be applied to show, the aspect such as printing.But, the ultrafine nanometer carbon black tool applied in this process
There is higher surface energy, the shortcomings of therefore there is difficult dispersion, easily reunite, and be difficult to dissolving in most solution, and Organic Black
Color dyestuff needs to carry out the technical process such as colorant match, colour mixture, and process is complicated and organic black dyes that prepare is unstable etc. lacks
Point.
In the last few years, semiconductor sulfide (such as zinc sulphide) material had much excellent performance such as in sewage because of it
Process, magneto-optic is changed, antibacterial, and the aspect such as photonic crystal receives significant attention.But, so far, also there is no document to utilization
The materials such as sulfide carried out report the preparation to prepare this shot-range ordered structure high saturation mechanism colour glaze.
