- Abstract
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 multipleordered structures from various polymers for applications in different areas.
