| 논문초록 | Polylactide (PLA) is the most commonly used biodegradable polymer for various fields such as biomedical and renewable industries. Unfortunately, the physical properties of PLA, such as the strength and crystallinity, are inevitably damaged during the molding process due to the slow crystallization. To overcome this limitation, a novel method for the in situ self-nucleating (ISN-) polymerization of L-lactide is developed. This strategy results in the simultaneous polymerization and self-nucleation of L-lactide crystallites upon addition of a self-nucleating agent. The results show that ISN-PLA experiences an acceleration effect on the crystallization with sc-PLA as the nucleating agent. The ISN-polymerization of L-lactide can save considerable time and cost by using the one-pot process composed of both polymerization and self-nucleation. This study suggests a novel strategy for manufacturing industrial products with high strength and crystallinity based on PLA as a promising biopolymer. |
