제목 The Effect of Glycidyl Methacrylate-grafted Polypropylene on the Thermal and Mechanical Properties of Polylactide-based Blends
초록 Polylactide (PLA) is a biodegradable, thermoplastic and aliphatic polyester, which is derived from renewable resources. However, the brittleness of PLA limits its practical applications in various commodity sectors. Polypropylene (PP), a commercial petroleum-based polymer, is widely used in commodity goods, due to its cost-effectiveness, good mechanical toughness and satisfactory heat resistance. In this study, to improve the physical properties of pristine PLA, PLA-based blends with glycidyl methacrylate-grafted PP (PPGMA) were fabricated via a efficient melt-compounding technique. The morphology, rheological, thermal and mechanical properties of PLA/PPGMA blends were investigated with aids of FT-IR, SEM, rheometer, DSC and DMA. The effect of PPGMA on the morphology, thermal and mechanical properties of PLA blends was analyzed by taking account of the PPGMA content and the reactivity between PPGMA and PLA.
