Description
Technical field
The invention belongs to photonic crystal structure color preparing technical field, gorgeous particularly to a kind of colour generation
SiO2The preparation method of colloidal crystal rainbow film.
Background technology
Schemochrome is when light is irradiated to body surface when, by visible ray and material physically
Microstructure interacts, the selective reflecting to some wavelength of generation and the effect of transmission, leads
Cause us and perceive color.Schemochrome phenomenon is much in nature, and such as blue sky is derived from
Rayleigh scattering, on the water surface, the color of oil stain is derived from film interference, and rainbow is derived from refraction etc..Schemochrome and thing
Matter micro structure is relevant with material character, as long as producing the physical property of the micro structure extremely material of schemochrome not
Becoming, schemochrome is will never fade.Schemochrome is to use structure to produce color, more more environmentally friendly than pigment.Traditional colour
The production of agent can cause a large amount of consumption of water resource, causes environmental pollution, and some toner is the most poisonous, can not
Degraded and fugitive color, so, schemochrome substituting tradition toner, false proof and furnishing fields has the most wide
Application prospect.
SiO2Colloidal crystal film is simple with its preparation technology, it is not necessary to special equipment, and preparation process will not
Any environmental pollution is caused to have potential advantage in schemochrome application aspect.At present, SiO2Colloidal crystal
Film is exactly to present faint iris in an outstanding problem of schemochrome application aspect, and color saturation is low,
Only veteran just can perceive color under specific angle, and colour generation is the most gorgeous, thus limit
Make its application.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide a kind of colour generation gorgeous
