High-Toughness Poly(lactic Acid)/Starch Blends Prepared through Reactive Blending Plasticization and Compatibilization

Molecules, 2020
In this study, poly(lactic acid) (PLA)/starch blends were prepared through reactive melt blending by using PLA and starch as raw materials and vegetable oil polyols, polyethylene glycol (PEG), and citric acid (CA) as additives.

Effect of talc and diatomite on compatible, morphological, and mechanical behavior of PLA/PBAT blends

e-Polymers, 2021
Biodegradable nanocomposites were prepared by melt blending biodegradable poly(lactic acid) (PLA) and poly(butylene adipate-co-butylene terephthalate) (PBAT) (70/30, w/w) with diatomite or talc (1–7%). From the SEM test, the particles were transported to

Effects of reactive compatibilization on the morphological, thermal, mechanical and rheological properties of intumescent flame retarded polypropylene

, 2009
Flame-retardant polypropylene (PP) samples were in situ compatibilized with maleic anhydride grafted PP. Compatibilization reaction was verified by an IR spectrum and gel content measurements.

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

Advanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed

PMMA/SAN and SAN/PBT nanoblends obtained by blending extrusion using thermodynamics and microrheogy basis

eXPRESS Polymer Letters, 2014
Styrene-Acrylonitrile (SAN) copolymer has been blended to poly(methyl methacrylate) (PMMA) and to poly(butylene terephthalate) (PBT) to obtain polymer nanoblends based on thermodynamics and microrheological aspects.
