Abstract

The invention relates to a composite structure chromogenic material with stable structure and a preparation method thereof, belonging to the field of new material preparation. A composite structural chromogenic material with stable structure, said material is obtained by superimposing transparent thermoplastic polymer and structural chromogenic material layer by layer and thermally bonding the surrounding edges of the polymer into a whole, the upper surface layer and the lower surface of the material The layers are all thermoplastic polymers. The forming composite structure of the present invention has relatively obvious structural color and good mechanical strength, which overcomes the disadvantage of poor structural stability of structural color-producing materials. The method is easy to operate, low in cost, can be applied in large areas, and can also be conveniently realized in patterning , suitable for daily necessities, packaging, decoration and other fields.

Description

technical field [0001] The invention relates to a composite structure chromogenic material with stable structure and a preparation method thereof, belonging to the field of new material preparation. Background technique [0002] Chemical dyeing pollution is the main source of industrial pollution. The dyeing and finishing process may produce a large amount of polluted wastewater and toxic substances, seriously affecting the ecological environment. At the same time, due to the influence of environmental factors, this chemical color may gradually fade or disappear. [0003] It is worth noting that structural color is considered as an alternative coloring route, which comes from the interaction of visible light with microscopic physical structure. Structural color is divided into iridescent and non-iridescent. Photonic crystal is a periodic ordered dielectric structure with photonic bandgap characteristics. When its photonic bandgap is in the visible wavelength range, photoni...
