Study of poly (l-lactic acid)/poly (d-lactic acid) stereocomplex as nucleating agent for poly (l- lactic acid) crystallization
… has some drawbacks. The Poly (lactic acid) (PLA) stereocomplex formed via the interaction between optical isomers Poly (L-lactic acid) (PLLA) and Poly (D-lactic acid) (PDLA), provides improvements on PLA thermomechanical properties. To investigate the nucleating effect brought by the PLA …

Stereocomplex poly (methyl methacrylate) fibers and self-reinforced composites and structural color of butterflies and beetles - characterization, replication and mimicry
Stereocomplex poly(methyl methacrylate) (PMMA) fibers for the purpose of reinforcing PMMA materials were developed. These kinds of composites are known as "self-reinforced" composites. We were successful in producing stereocomplex PMMA fibers with three different methods - wet spinning, gel …

Optically pure D (-) lactic acid biosynthesis from diverse renewable biomass: microbial strain development and bioprocess analysis
… of PDLA with PLLA results in a heat-resistant stereocomplex PLA with excellent properties. As a consequence, large quantity of cost effective D-lactic acid is required to meet the demand of stereocomplex PLA. Lignocellulosic biomass is a promising feedstock for lactic acid production because of …

Novel PLA-based materials with improved thermomechanical properties and processability through control of morphology and stereochemistry. A study in improving toughness and processability of PLA by blending with biodegradable polymers and the two PLA enantiomers PLLA and PDLA to accelerate crystallinity and heat resistance
… a processing model of developing a fully stereocomplex PLA part based in commercial techniques is proposed. Injection moulded PLA showed even higher heat resistance without the need of further processing the product (increasing crystallinity).
