Melt blending poly(l-lactide) (PLLA) with various biodegradable polymers has been thought to be the most economic and effective route toughen PLLA without compromising its biodegradability. Unfortunately, only very limited improvement in notched impact toughness can achieved, although of these blends show significant enhancement tensile toughness. In this work, poly(ε-caprolactone) (PCL) was used as an modifier a nucleating agent utilized tailor crystallization matrix. Depending on...
The microstructure and mechanical properties of β-nucleated iPP before after being annealed at different temperatures (90−160 °C) have been analyzed. Annealing induced degrees variation in fracture toughness samples, namely, slight enhancement relatively low annealing (<110 great improvement moderate (120−130 °C), whereas dramatic deterioration high (>140 has observed. is observed to be dependent on the content β-NA. Experiments, including scanning electronic microscope (SEM), wide-angle...

Recently, some attempts have been made to enhance the gas barrier properties of semicrystalline polymers by precisely controlling arrangement their impermeable crystalline lamellae. However, it is still a great challenge achieve regular lamellae along direction perpendicular diffusion path, especially using conventional polymer processing technologies. This work presents novel and simple strategy dramatically improve oxygen performance biobased biodegradable polylactide (PLA) through...
As an eco-friendly polymer with tremendous potential to replace traditional petroleum-based and nonbiodegradable polymers, the current use of poly(l-lactide) (PLLA) in large-scale commercial applications still faces some barriers mostly associated its inherent brittleness poor heat resistance. In this work, we propose a novel facile strategy simultaneously address these obstacles by introducing small amounts poly(d-lactide) (PDLA) into thermoplastic polyurethane (TPU) toughened PLLA blends...
Stereocomplexation of enantiomeric poly(l-lactide)/poly(d-lactide) (PLLA/PDLA) chains opens up a great opportunity toward sustainable PLA engineering plastic with exceptional heat resistance and durability. However, the processing applications stereocomplex-type (SC-PLA) are significantly blocked by its inferior melt stability (i.e., weak memory effect in triggering complete SC crystallization, which makes it hard to obtain exclusive formation crystallites melt-processed products) inherent...
Inorganic nanofillers are often added into polymer/elastomer blends as a third component to modify their performance.This work aims clarify the role of interface-localized spherical nanoparticles in determining impact toughness polymer blends.The selective distribution titanium dioxide (TiO 2 ) poly(L-lactide)/poly(ether) urethane (PLLA/PU) was investigated by using scanning electron microscope.It is interesting find that, regardless method TiO introduction, nano-TiO particles always...

Abstract Stereocomplexation between enantiomeric poly( l -lactide) (PLLA) and d (PDLA) provides an avenue to greatly enhance performance of eco-friendly polylactide (PLA). Unfortunately, although the manufacturing semicrystalline polymers generally involves melt processing, it is still hugely challenging create high-performance stereocomplexed (sc-PLA) products from melt-processed high-molecular-weight PLLA/PDLA blends due weak crystallization memory effect stereocomplex (sc) crystallites...
