Patterned photonic crystals with structural colors on textile substrates have attracted a special attention due to the great advantages in application, which currently become a research hot-spot. This study utilized an ink-jet printing technology to prepare high-quality photonic crystal patterns with structural colors on polyester substrates. The self-assembly temperature of poly(styrene-N-methylol acrylamide) (P(St-NMA)) microspheres set to construct photonic crystals were deeply optimized. Moreover, the structural colors of prepared photonic crystal patterns were characterized and evaluated. When the mass fraction of P(St-NMA) microspheres was 1.0 wt.%, the pH value ranged from 5 to 7, and the surface tension was in the range of 63.79 to 71.20 mN/m, inks could present the best print performance. At 60 °C, prepared P(St-NMA) microsphere inks were good for printing to obtain patterned photonic crystals with regular arrangement and beautiful structural colors. Specifically, photonic crystals with different colors could be constructed by regulating the diameter of microspheres in inks, and prepared structural colors exhibited distinct iridescent phenomenon. The present results could provide a theoretical basis for the industrial realization of patterned photonic crystals by ink-jet printing technology.

由于其在应用中的巨大优势，在纺织品基材上具有结构色的图案化光子晶体引起了人们的特别关注，目前已成为研究热点。这项研究利用喷墨打印技术在聚酯基板上制备具有结构色的高质量光子晶体图案。深入优化了用于构建光子晶体的聚苯乙烯-N-羟甲基丙烯酰胺（P（St-NMA））微球的自组装温度。此外，表征和评估了所制备的光子晶体图案的结构颜色。当P（St-NMA）微球的质量分数为1.0 wt。％，pH值为5至7，表面张力为63.79至71.20 mN / m时，油墨可以表现出最佳的打印性能。在60°C下，制备的P（St-NMA）微球油墨适合印刷以获得规则排列和美丽结构颜色的图案化光子晶体。具体而言，可以通过调节油墨中微球的直径来构造具有不同颜色的光子晶体，并且所制备的结构色表现出明显的虹彩现象。本研究结果可为通过喷墨印刷技术实现图案化光子晶体的工业化提供理论依据。
