P(St-MAA)@PDA微球的制備及其在白色絲綢光子晶體結構生色中的應用

摘 要： 為實現白色底色絲綢的結構生色，以黑色的聚多巴胺（PDA）為殼，以聚（苯乙烯-甲基丙烯酸）（P（St-MAA））微球為核，采用乳液聚合法制備“核殼型”P（St-MAA）@PDA微球；并以該微球為結構基元，采用真空輔助過濾方式，在絲綢基底上構筑光子晶體生色結構。考察多巴胺（DA）用量對P（St-MAA）@PDA微球粒徑和形貌的影響，分析P（St-MAA）@PDA微球的基本性能，探究PDA層厚度對光子晶體結構生色的影響，并對白色絲綢上構筑所得P（St-MAA）@PDA光子晶體結構生色的效果進行評價。結果表明：在P（St-MAA）微球粒徑確定的情況下，隨著DA用量的增加，P（St-MAA）@PDA微球的粒徑不斷增大；制備所得P（St-MAA）@PDA微球分布均勻，球形度及單分散性良好，適宜構筑光子晶體生色結構；當PDA的厚度為3.5～9.0 nm時，P（St-MAA）@PDA微球在白色絲綢上可顯現出明顯且均勻的光子晶體結構色，且隨微球粒徑的增大結構色發生紅移現象；P（St-MAA）@PDA微球所構筑的光子晶體生色結構具有優異的穩固性。該研究為白色底色絲綢上光子晶體生色結構的構筑提供了理論依據。

Abstract：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 microspheres increased with the increase of DA dosage when the particle size of P（St-MAA） microspheres was determined; the prepared P（St-MAA）@PDA microspheres were uniformly distributed， with good sphericity and monodispersity， and were suitable for the construction of photonic crystals with structural colors; the P（St-MAA）@PDA microspheres could show obvious and uniform photonic crystals with structural colors on white silk when the thickness of PDA was controlled within the range of 3.5 nm and 9.0 nm; the structural colors were red-shifted with the increase of microspheres particle size; the photonic crystals with structure colors constructed by P（St-MAA）@PDA microspheres had excellent stability. This study provides a theoretical basis for the construction of photonic crystals with structure colors on white silk.

采用染料、顏料等色素著色是當前實現紡織品著色的主要途徑，但這類方式普遍存在高污染、高耗能、高排放等弊病^［1-3］。近年來，以微球為結構基元構筑周期性排列的光子晶體，通過光的衍射作用可獲得結構色，從而實現紡織品著色，這類研究層見迭出^［4-6］。……
