英文摘要	This study aims at investigating the influence of supercritical carbon dioxide (ScCO2) treatment on the physicochemical properties of cassava–based cellulose. The ScCO2 treatment was performed in a high-pressure vessel by exposing the cellulose to ScCO2 without a co-solvent at variable pressure (P) ranging from 8 MPa to 20 MPa for 60 min. The system temperature (T) was set to 40 °C, 60 °C and 80 °C. Subsequently, a field emission scanning electron microscopy analysis showed that the average fibril diameter of the cellulose was approximately two times less than that of the untreated cellulose. Differential scanning calorimetry and thermogravimetric analyses showed higher temperature shifting of the decomposition peak, which indicated improved thermal stability of the ScCO2-treated celluloses. Additionally, a correlation test revealed that thermal stability of cellulose increased with the pressure of ScCO2. Elsevier B.V.
