| titleOfInvention | A kind of photonic crystal pigment and preparation method thereof |
| abstract | The invention discloses a photonic crystal pigment and a preparation method thereof, belonging to the technical field of photonic crystal pigment preparation. The preparation method of the photonic crystal pigment comprises any one of the following methods: (1) After blending two amphiphilic block copolymers with different molecular weights to obtain a blend, the blend is dissolved in an organic solvent, filtered , the filtrate is added in the surfactant solution, after emulsification, the organic solvent is volatilized to obtain the photonic crystal pigment; (2) the amphiphilic block copolymer is brushed with the lipophilic homopolymer (polystyrene homopolymer HS ) after blending to obtain a blend, dissolve the blend in an organic solvent, filter, add the filtrate to a surfactant solution, and after emulsification, volatilize the organic solvent to obtain the photonic crystal pigment. The invention has simple preparation steps, avoids the process of preparing full-spectrum structural color by synthesizing a large number of polymer brushes with precise molecular weight, and embodies high efficiency. |
