Owing to the strong solid-state luminescence of aggregation-induced emission luminogen (AIEgen), polymer/AIEgen nanoparticles (NPs) have great potential in application as high-quality luminescent inks. In this work, polymer/AIEgen NPs with a particle size below 70 nm were efficiently prepared through encapsulation of AIEgens with various colors within polymeric matrix via miniemulsion polymerization. The prepared polymer/AIEgen NPs emitted bright and stable blue, green, or orange-red fluorescence. The polymer/AIEgen NP inks suitable for inkjet printing were conveniently made through addition of a non-ionic surfactant to the emulsions with corresponding polymer/AIEgen NPs. The bright, high-resolution, and UV-responsive images were printed on cotton textiles with polymer/AIEgen NP inks. The microscopic observation indicated that the polymer/AIEgen NPs could form homogenous films onto the cotton fibers. More promisingly, the prepared polymer/AIEgen NPs with various colors had good compatibility, and they could be directly mixed to prepare multicolor polymer/AIEgen NP inks for handwriting.

由于聚集诱导的发射发光剂（AIEgen）的强固态发光，聚合物/ AIEgen纳米颗粒（NPs）作为高质量的发光油墨具有巨大的应用潜力。在这项工作中，通过细乳液聚合将各种颜色的AIEgens封装在聚合物基质中，可以有效地制备粒径小于70 nm的聚合物/ AIEgen NP。制备的聚合物/ AIEgen NP发出明亮，稳定的蓝色，绿色或橙红色荧光。通过将非离子表面活性剂添加到带有相应聚合物/ AIEgen NP的乳液中，可以方便地制得适用于喷墨印刷的聚合物/ AIEgen NP油墨。使用聚合物/ AIEgen NP墨水将明亮，高分辨率和紫外线响应的图像打印在棉纺织品上。显微镜观察表明，聚合物/ AIEgen NPs可以在棉纤维上形成均匀的薄膜。更有希望的是，所制备的各种颜色的聚合物/ AIEgen NP具有良好的相容性，可以将它们直接混合以制备用于手写的多色聚合物/ AIEgen NP油墨。
