| Research Abstract |
The aim of this study was to develop a strategy for direct pattern transferring of CNT self-assembled micro-structures. Efficient individual solubilization of carbon-nanotubes(CNTs) was successfully achieved by using biological molecule of sodium deoxycholate(SDC). By controlling the concentrations of SDC and CNT in suspension, the viscoelastic response of CNT colloid was enhanced, and the hydrogel was obtained. The hydrogel showed the unique plastic deformation under elongational flow, resulting in thin and long filaments. We have successfully conducted the directed self-assembly of CNT patterns using the hydrogel as a printable ink.
