The helix and superhelix play critical roles in the achievement of tissue functions. These fascinating structures have attracted increasing interest due to their potential biomimicking applications. However, continuous and controlled fabrication of these structures, especially the superhelical structures, from various polymers for different practical applications still remains a big challenge. Here, a novel and versatile microfluidic spinning strategy is presented for generation of both helical and superhelical microfibers from either hydrophilic, hydrophobic, or amphiphilic polymers. The diameter (d ), wavelength (λ), and amplitude (A) of these microfibers could be highly controlled. The helical microfibers show outstanding elongations and potential applications in magnetic responsive elastic microactuators. It is envisioned that these results will greatly enrich the possibility of generating new multiple-ordered structures from various polymers for applications in different areas.
螺旋和超螺旋结构在实现组织功能方面发挥着关键作用。由于它们具有潜在的仿生应用，这些迷人的结构引起了越来越多的关注。然而，从各种聚合物中连续和可控地制造这些结构，特别是超螺旋结构，对于不同的实际应用仍然是一个巨大的挑战。在这里，提出了一种新颖而通用的微流控纺丝策略，用于从亲水性、疏水性或两亲性聚合物中生成螺旋和超螺旋微纤维。这些微纤维的直径 (d)、波长 (λ) 和幅度 (A) 可以高度控制。这些螺旋微纤维具有出色的伸长率，在磁响应弹性微致动器中有潜在的应用。可以预见，这些结果将极大地丰富了从各种聚合物中生成新的多阶结构的可能性，以应用于不同领域。
