Abstract

Micropatterning of biological surfaces performed via assembly of nano-blocks is an efficient design method for functional materials with complex organic-inorganic architecture. Halloysite clay nanotubes with high aspect ratios and empty lumens have attracted widespread interest for aligned biocompatible composite production. Here, we give our vision of advances in interfacial self-assembly techniques for these natural nanotubes. Highly ordered micropatterns of halloysite, such as coffee rings, regular strips, and concentric circles, can be obtained through high-temperature evaporation-induced self-assembly in a confined space and shear-force brush-induced orientation. Assembly of these clay nanotubes on biological surfaces, including the coating of human or animal hair, wool, and cotton, was generalized with the indication of common features. Halloysite-coated microfibers promise new approaches in cotton and hair dyeing, medical hemostasis, and flame-retardant tissue applications. An interfacial halloysite assembly on oil microdroplets (Pickering emulsion) and its core-shell structure (functionalization with quantum dots) was described in comparison with microfiber nanoclay coatings. In addition to being abundantly available in nature, halloysite is also biosafe, which makes its spontaneous surface micropatterning prospective for high-performance materials, and it is a promising technique with potential for an industrial scale-up.

用功能性粘土纳米管对生物表面进行微图案化。
通过组装纳米块对生物表面进行微图案化是一种高效的设计方法,可设计出具有复杂有机-无机结构的功能材料。具有高纵横比和空腔的埃洛石粘土纳米管在对准生物相容性复合材料生产方面引起了广泛的兴趣。在此,我们对这些天然纳米管的界面自组装技术的进展进行了展望。通过高温蒸发诱导的密闭空间自组装和剪切力刷诱导的取向,可以获得高度有序的埃洛石微图案,如咖啡环、规则条带和同心圆。这些粘土纳米管在生物表面(包括人或动物的毛发、羊毛和棉花的涂层)上的组装被概括为共同的特征。埃洛石涂层微纤维有望成为棉花和毛发染色、医疗止血和阻燃组织应用的新方法。通过与超细纤维纳米粘土涂层的比较,介绍了油微滴(皮克林乳液)上的界面埃洛石组装及其核壳结构(量子点功能化)。埃洛石不仅在自然界中含量丰富,而且还具有生物安全性,这使其自发表面微图案化技术在高性能材料领域大有可为,是一项具有工业放大潜力的技术。
