Fabrication of Mechanically Tough Dry-Free Ionogel Microfibers Swollen in Aqueous Electrolyte by Microfluidic Devices |
| 초록 |
Fiber shape soft conducting materials have demonstrated many advantages and promising potentials for development of soft electronics. In this work, highly stretchable conducting microfibers is prepared using microfluidic devices comprising co-axial aligned micro-capillaries. Double network structure of hydrogel microfibers is obtained through the coagulation of chitosan in cold water and simultaneous crosslinking of N-isopropylacrylamide and N-diethylacrylamide via photo-polymerization. Furthermore, the prepared hydrogel microfibers are immersed in crosslinking agent solution to reinforce chitosan chains and exchange of the medium of the hydrogel microfiber with an aqueous electrolyte of lithium bis(trifluoromethanesulfonyl)imide. The ionogel fibers shows high conductivity and stretchability as well as dry-free properties. Owing to its mechanical robustness and ionic conductivity, we envision a highly stretchable soft electrode with the prepared ionogel microfiber. |
