| 초록 | A biodegradable and sustainable polymer composite (BSPC) based on polylactic acid (PLA) and microfibrillated cellulose (MFC) is prepared, and its mechanical properties are examined in this study. PLA-coated MFCs are prepared by blending PLA colloids and MFCs in an aqueous solution. While pristine MFCs are intrinsically highly aggregated with each other due to strong intermolecular hydrogen bonding interaction, PLA colloids induce effective exfoliation of aggregated MFCs. BSPC is then produced by thermally blending PLA with PLA-coated MFCs. It is concluded that the improved compatibility between PLA and PLA-coated MFCs is responsible for the excellent mechanical properties of BSPC compared to pure PLA. |
