| Outline of Final Research Achievements |
The aims of this study are the production of new bio-based plastics from non-edible biomass and the high-functionability of biodegradable plastics. Xylan, one of hemicelluloses extracted from wood, was esterified to add the thermos-plasticity and we succeed to process the flexible films and nanofibers. And also, it was found that xylan ester derivatives became a good nucleate agent for poly(lactic acid) that is the most important bio-based and biodegradable plastic. On the other hand, ultra-high-molecular-weight microbial polyesters have been synthesized and succeeded to process the high tensile strength films and fibers. The molecular and crystals structures were analyzed by the X-ray diffraction at synchrotron radiation. Furthermore, it was revealed that the rate of enzymatic degradation can be controlled by the crystallinity and molecular structures.
