Outline of Final Research Achievements

Using the new technique Teslaphoresis, I could align the carbon nanotubes in synthetic hydrogel using supramolecular interactions. The hydrogel showed enhanced mechanical strength and stability. Furthermore, we investigated the anisotropic properties, such as conductivity of the hydrogel-carbon nanotube hybrids. depending on the direction of the alignment, we could enhance the conductivity of the gel in certain directions. In another related topic, we used the pluronic hydrogels as receptor materials for the membrane-type surface stress sensor MSS to detect various gasses. We observe that the direction of the alignment of carbon nanotubes strongly affects the sensitivity. In some cases we could enhance over 1000 times the sensitivity of the sensor materials. This remarkable finding is now under further investigation.

Academic Significance and Societal Importance of the Research Achievements

The result of this investigation extends the academia and has many applications in real world.
We can now make stronger hydrogels using aligned carbon nanotubes for stronger water-like materials. We could detect small concentration of gases using this hydrogel, useful for agricultural applications.
