Cellulose-based bioplastics have been developed to reduce the use of synthetic plastics. In this work, a renewable material, cellulose-cysteine was synthesized using the esterification method to improve mechanical properties by adding disulfide bonds therein. Avicel PH101 and PH102 were used as raw materials for the manufacture of cellulose-cysteine. The SEM-EDX analysis showed that cysteine was successfully grafted with 1.44-1.72% on sulfur element content with a rougher surface structure than avicel. The FT-IR peak at 1749 cm-1 and 1429 cm-1 showed the presence of C=O esters and N-H groups of cysteine, respectively. Thus, it was confirmed that cysteine has bound to cellulose. © 2023 American Institute of Physics Inc.. All rights reserved.
