摘要

由于生物可降解性等诸多优异性能，聚乳酸材料的研究一直受到广泛关注. 然而，聚乳酸的韧性较差，这限制了其应用范围. 本研究首先将右旋聚乳酸(poly(

-lactic acid)

PDLA)与聚乙烯醇(poly(vinyl alcohol)

PVA)反应，制备了接枝物PVA-

-PDLA，并对PVA-

-PDLA进行表征. 其次，以六氟异丙醇(HFIP)为溶剂，将PVA-

-PDLA添加至聚乳酸外消旋共混物(poly(

-lactic acid)/poly(

-lactic acid)

PLLA/PDLA)中，制备了PVA-

-PDLA/PLLA/PDLA复合材料. 该复合材料经溶液浇铸形成的是同质晶，这被证明与所使用的溶剂有关. 再次，对PVA-

-PDLA/PLLA/PDLA复合材料进行了力学性能测试. 结果表明，PVA-

-PDLA/PLLA/PDLA的断裂伸长率最高可达200%. 最后，本文以PVA-

-PDLA/PLLA为参照，探讨了PVA-

-PDLA对全同质晶聚乳酸外消旋共混物的增韧机理.

Abstract

Poly(lactic acid) (PLA)

derived from bio-renewable resources

exhibits numerous advantageous properties

including biodegradability

and is anticipated to substitute petroleum-based polymers in various applications. Consequently

research on PLA materials has garnered significant attention. However

the inherent brittleness of PLA restricts its broader application. In this study

we conducted molecular-level modifications and design of PLA. Initially

right-handed poly(lactic acid) (PDLA) and poly(vinyl alcohol) (PVA) underwent dehydration condensation to synthesize the graft copolymer PVA-

-PDLA. Characterization

via

NMR

FTIR

and TGA confirmed a reduction in hydroxyl group content and an increase in ester group content

thereby validating the successful synthesis of PVA-

-PDLA. Subsequently

using hexafluoroisopropanol (HFIP) as the solvent

PVA-

-PDLA was incorporated into the racemic copolymer of poly(lactic acid) (PLLA/PDLA) at varyin

mass ratios to prepare PVA-

-PDLA/PLLA/PDLA composites. XRD analysis indicated that the solution-cast composites exhibited homogeneous crystallinity

which was attributed to the choice of solvent. Mechanical propert

y tests revealed that the elongation at break of the composites increased with higher PVA-

-PDLA content

reaching up to 200%. Finally

by referencing PVA-

-PDLA/PLLA

the toughening mechanism of PVA-

-PDLA on the racemic copolymer of isotactic poly(lactic acid) was elucidated.
