Abstract

: The poly(L-lactide) films properties were improved by using cellulose from rice straw. The cellulose was extracted by hydrolysis method and that was confirmed the property by using Fourier transforms infrared spectroscopy (FT-IR). The sample films were prepared by mixing poly(L-lactide) with cellulose at different weight ratios (100/0, 98/2, 96/4, 94/6, 92/8, 90/10). Physical, mechanical and thermal properties of the films were analyzed by X-Ray diffraction (XRD), Scanning Electron Microscope (SEM), Thermogravimetric Analysis (TGA) and Tensile testing. It was found that after increasing the concentration of the cellulose to 2 %wt, the tensile strength increases from 24.949 to 37.108 MPa and Young's Modulus slightly increase from 0.112 to 0.189 GPa. The thermal stability of the sample films increased slightly. These results showed that cellulose from rice straw was enhanced to develop the thermal and mechanical properties of poly(L-lactide) film. The water uptake increased with the addition of cellulose.
