| Outline of Final Research Achievements |
In order to establish a method for unraveling and fiberizing cellulose microfibrils with dry pulverization, the ozone assist pulverization was investigated to promote the unraveling. As a result, although the effect of untangling the fibers by the addition of ozone was confirmed, it was difficult to realize a device configuration that allows ozone to act stably. However, when the aggregation inhibitory effect was given using acetylation, an effect equal to or greater than that of ozone was obtained.
