As a simple and facile fabrication technique, microfluidic devices based on coaxial flow have been used to fabricate hydrogel microfibers via photo-polymerization. In this work, we prepared mechanically tough meter-long double network (DN) hydrogel microfibers using microfluidic devices consisting co-axial aligned micro-capillaries. The developed hydrogels are further reinforced by the ionic and covalent crosslinking. Furthermore, by immersing prepared hydrogel into the ionic liquid (ILs), tough and stretchable as well as stable microfibers could be produced. Both hydrogel and ionogel microfibers show high mechanical properties, having such a high potential soft material system of continuous microfibers which can be easily produced through microfluidic technique. |
