以生物质多糖微球为模板的反蛋白石生色材料的构建与性能

有机发色体系结构众多，生产流程长，很多染料生产和使用的安全环境问题、还有一些染料的牢度性能等都需要逐个解决。结构生色材料不使用有机共轭体系，因而不存在相应的问题。本项目拟设计制造出以生物质多糖微球为模板、以折射率、韧性及抗张力性能可调控的填充材料制造反蛋白石生色材料，(1) 研究生物质模板材料及均匀微球制造、蛋白石结构组装和酶解去除模板方案，以保证反蛋白石结构规整和稳定；(2) 设计开发出性能可调控的金属离子交联网络高分子填充材料；(3) 制备出颜色、厚度、韧性和抗张力性能可调的结构稳定的反蛋白石生色材料；(4) 研究该材料的介电常数、折射率、结构、厚度等与颜色的关系；(5) 研究反蛋白石结构作为着色材料、显示材料等应用的可行性，为结构生色材料作为化工新材料提供理论依据和技术可行性。

A number of problems concerning organic chromogenic conjugated system are required to solve, which include over many structures, long production process, serious safety and environmental issues in production and application of many dyes, as well as unsatisfactory fastness properties of some of them. However, structural color materials have no such disadvantages because structural color is not aroused by organic conjugated system. This project designs to manufacture inverse opal structural color materials using biomass polysaccharide microspheres as templates and materials with adjustable refractive index, toughness and tensile properties as fillings. It aims to (1) study the biomass template materials and manufacture of their uniform microspheres, and the programs of opal structure assembly and removal of the template by enzymolysis for ensuring stable and highly ordered inverse opal structure; (2) design and develop metal-crosslinked space network polymeric fillings with adjustable properties; (3) prepare stable inverse opal structural color material with adjustable color, thickness, toughness and tensile properties; (4) investigate the relationship between the dielectric constant, refractive index, structure, thickness and color of the materials; and (5) study the application feasibility of inverse opal structural color materials as coloring and display materials, to provide a theoretical basis and technical feasibility for structural color materials as new chemical materials..Keywords: inverse opal; structural color materials; polysaccharide microsphere template; enzymolysis; metal-crosslinked space network polymeric
