Abstract: The present disclosure provides a polylactic acid composition and a method of preparing the same. The polylactic acid composition comprises a polymeric material and a reaction product obtained by reacting a compound represented by formula (A) with a compound represented by formula (B), the polymeric material comprising polylactic acid, the compound represented by formula (A) being a trimeric phosphazene-based substance, and the compound represented by formula (B) being diamine. The polylactic acid composition is favorable in both flame retardancy and toughness.

Abstract: Provided are use of a rare earth amino acid complex, a polylactic acid composition and a preparation method thereof. The rare earth amino acid complex is formed by complexing a rare earth metal ion with an amino acid; a rare earth element corresponding to the rare earth metal ion is one or more selected from the group consisting of lanthanum, cerium and samarium; and the amino acid is at least one selected from the group consisting of proline, L-phenylalanine, tyrosine and tryptophan.
