摘　　要：为实现白色底色丝绸的结构生色,以黑色的聚多巴胺(PDA)为壳,以聚(苯乙烯-甲基丙烯酸)(P(St-MAA))微球为核,采用乳液聚合法制备“核壳型”P(St-MAA)@PDA微球;并以该微球为结构基元,采用真空辅助过滤方式,在丝绸基底上构筑光子晶体生色结构。考察多巴胺(DA)用量对P(St-MAA)@PDA微球粒径和形貌的影响,分析P(St-MAA)@PDA微球的基本性能,探究PDA层厚度对光子晶体结构生色的影响,并对白色丝绸上构筑所得P(St-MAA)@PDA光子晶体结构生色的效果进行评价。结果表明:在P(St-MAA)微球粒径确定的情况下,随着DA用量的增加,P(St-MAA)@PDA微球的粒径不断增大;制备所得P(St-MAA)@PDA微球分布均匀,球形度及单分散性良好,适宜构筑光子晶体生色结构;当PDA的厚度为3.5~9.0 nm时,P(St-MAA)@PDA微球在白色丝绸上可显现出明显且均匀的光子晶体结构色,且随微球粒径的增大结构色发生红移现象;P(St-MAA)@PDA微球所构筑的光子晶体生色结构具有优异的稳固性。该研究为白色底色丝绸上光子晶体生色结构的构筑提供了理论依据。To realize the structural colors of silk with a white background,“core-shell”P(St-MAA)@PDA microspheres were prepared by emulsion polymerization with black polydopamine(PDA)as the shell and poly(styrene-methacrylic acid)(P(St-MAA))colloidal microspheres as the core,and photonic crystals with structural colors were constructed on silk substrates by vacuum-assisted filtration using them as the structural units.The effect of dopamine(DA)dosage on the particle size and morphology of P(St-MAA)@PDA microspheres was investigated,the basic properties of P(St-MAA)@PDA microspheres were analyzed,the effect of the thickness of the PDA layer on the photonic crystals with structural colors was explored,and the effect of the P(St-MAA)@PDA photonic crystals with structure colors constructed on white silk were evaluated. The results showed that the particle size of P(St-MAA)@PDA microspheresincreased with the increase of DA dosage when the particle size of P(St-MAA) microspheres wasdetermined;the prepared P(St-MAA)@PDA microspheres were uniformly distributed, with goodsphericity and monodispersity, and were suitable for the construction of photonic crystals with structuralcolors;the P(St-MAA)@PDA microspheres could show obvious and uniform photonic crystals withstructural colors on white silk when the thickness of PDA was controlled within the range of 3.5 nm and9.0 nm;the structural colors were red-shifted with the increase of microspheres particle size;the photoniccrystals with structure colors constructed by P(St-MAA)@PDA microspheres had excellent stability. Thisstudy provides a theoretical basis for the construction of photonic crystals with structure colors on whitesilk.
