| Outline of Final Research Achievements |
We have proposed novel amorphization technique for polysaccharides such as starch and cellulose by using mill machines equipped with temperature control units. In particular, low temperature milling at 10oC is effective to obtain amorphous cellulose. In this project we tried to make the amorphization technique to develop into a reactive milling technique which enables simultaneous operations of milling and chemical modification. We expect that structural change from crystal to amorphous will also give a chance for chemical modification. We added maleic anhydride to cellulose and milled it showing a possibility of esterification of cellulose under milling. It was found that general plastic materials such as polylactic acid and nylon etc. can be also amorphized by this milling machine. In addition, we showed that amorphized cellulose is superior to usual crystalline cellulose when they are used for composite with resin material.
