| Outline of Final Research Achievements |
Xylem of coniferous trees has well-ordered micro-honeycomb structures, and this makes wood a light and tough material. In this work, we have successfully fabricated a similar micro-honeycomb structure from cellulose which is the main component of natural trees. While in natural xylem honeycomb pores are blocked, the artificial xylem prepared has penetrating pores, thereby allowing fluid flow with very low pressure drop. Another advantage of the artificial xylem is its chemical controllability. We succeeded to prepare a variety of artificial xylem with different functions by changing the chemical properties of the honeycomb walls.
