| Abstract: | Rare earth nucleating agent/polylactide(PLA) composites were prepared by in situ polymerization.Optical depolarization,X-ray diffraction,temperature-deformation curve,and thermal gravimetric analysis were employed to characterize the crystallization behavior and thermal property of the obtained composites.The results showed that,compared with the pure PLA,the crystallization rate and crystallinity of the composites increased greatly.When the content of the rare earth nucleating agent reached 2%,the crystall... |
