Abstract

The invention discloses a self-assembly substance based on a brush-like block polymer and a synthesis method and application thereof. The method for synthesizing the self-assembly substance comprisesthe following steps: uniformly dispersing the brush-like block copolymer PNBPM-b-PNDM in tetrahydrofuran, coating the mixed solution on a glass slide, and performing solvent evaporation at room temperature to obtain a polymer film. The self-assembly substance makes photonic crystal materials can be applied to light sensors, light valves, pigments, dyes and other aspects, and has great practical value.

Description

technical field

[0001] The invention relates to the technical field of preparation of brush-like block copolymers, in particular to a self-assembly based on brush-like block polymers and its synthesis method and application. Background technique

[0002] Due to the existence of the internal photonic bandgap structure, photonic crystals can regulate the propagation of light waves, so that they have great application value, such as making special pigments, waveguides and reflective coatings, etc. Responsive photonic crystals are a class of materials whose reflection wavelength can change with changes in external physical or chemical conditions. In addition to the periodic structure necessary for traditional photonic crystals, this material must also have responsive groups. There are two common ways to introduce responsive groups: (1) Use responsive materials as substrates to directly construct photonic crystal structures, such as using block polymer self-assembly to prepare o...
