| Outline of Annual Research Achievements |
Using synthetic gelators we could to align the carbon nanotubes (CNTs) inside of the gels. The aligned CNTs were successfully stabilized by forming hydrogels around them. Different types of gelators were tested, but only one seemed to work for our intended application. This had to do with gelation time and gel strength, which were optimal for 0.3 wt.% gels from gelator. The mechanical properties of the materials (CNT-containing gels, both aligned and non-aligned, and blanks) were studied using oscillatory rheology. The CTNs increased the yield strain of the gels, this difference was even more profound when they were aligned in a direction parallel to the direction of the oscillation. Finally, the conductivity of the gels was tested. The resistance was measured along, and perpendicular to, the direction of the self-assembled CNTs wires. These were compared to blanks without CNTs and with randomly oriented CNTs. The results of these experiments show that the direction of the alignment of the CNTs affects the conductivity. In summary: the use of Teslaphoresis, to make aligned CNT hydrogels, allowed us to study the effect of this alignment on the mechanical and conducting properties of the materials.
