| Abstract: |
| In this study， cellulose nanofibrils （CNFs） and dodecenyl succinic anhydride （DDSA） were used as raw materials to prepare dodecenyl succinic anhydride-modified cellulose nanofibrils （D-CNFs） by the wet processing， and the structure of D-CNFs were characterized by FT-IR， Zeta-potential， TG， water contact angle， and XRD. The results showed that the optimal conditions for preparing D-CNFs were reaction temperature， pH value， and reaction time of 40℃， 8.5， and 6 h， respectively. The as-prepared product was of a water contact angle of 83.2° and good thermal stability， forming a stable suspension system which could provide more selectivity for its future applications in food， medicine， and other fields， possessing potential application value. |
