Compatibilization of biopolymer blends: A review

Advanced Industrial and Engineering Polymer Research, Год журнала: 2023, Номер 7(4), С. 373 - 404

Опубликована: Ноя. 14, 2023

Biopolymers from renewable bio-based resources provide a sustainable alternative to petroleum-derived plastics, but limitations like brittleness and cost restrict applicability. Blending offers an affordable route combine the advantages of different biopolymers for tailored performance. However, most biopolymer pairs are intrinsically immiscible, necessitating compatibilization obtain optimal blend morphology, interfacial interaction, properties. This review summarizes key strategies recent advances in tailoring blends. Non-reactive techniques using block or graft copolymers can increase compatibility, though property enhancements often modest. More impactful reactive methods, which functionalize form compatibilizing in-situ during melt-blending. Nanoparticle incorporation also effectively compatibilizes through interface localization morphology control. These enable significant toughening poly(lactic acid) (PLA) other brittle biopolyesters by blending with ductile polymers such as poly(butylene adipate-co-terephthalate)((PBAT) elastomers natural rubber. Properly compatibilized PLA blends exhibit major simultaneous improvements elongation, strength, impact resistance. Using inexpensive starch decreases requires maintain adequate Nanoparticles additionally impart functionality barrier flame retardance. quantitatively correlating processing, properties will further optimization. Developing chemistries nanoparticles potential beyond conventional techniques, retaining biodegradability is crucial. Overall, facilitates synergistic combinations complementary biopolymers, providing eco-friendly, high-performance, cost-effective alternatives traditional plastics across diverse applications.

Improvement of Poly(lactide) Ductile Properties by Plasticization with Biobased Tartaric Acid Ester

Macromolecular Materials and Engineering, Год журнала: 2023, Номер 308(7)

Опубликована: Фев. 9, 2023

Abstract Diethyl l ‐tartrate (DET) is used as a biobased plasticizer for poly(lactide) (PLA) formulations with improved ductile properties without compromising biodegradation. Different weight percentages (wt.%) of DET in the 0–50 wt.% range are added to PLA by melt compounding and subsequently processed injection molding. The effect on mechanical, thermal, thermo‐mechanical, morphology, biodegradation, crystallinity studied. Addition 20 leads noticeable increase elongation at break up values 567%, which quite an interesting result considering extreme brittleness PLA. These results verified field emission scanning electron microscopy (FESEM) images, where filament‐like structures observed, indicative effective plasticization. Differential calorimetry (DSC) dynamic mechanical thermal analysis (DMTA) show that glass transition temperature drastically decreased down 23 °C sample highest amount (50 wt.%), thus increasing its ductility processability. Fourier‐transformed infrared spectroscopy (FTIR) spectra there exists chemical interactions between DET. Finally, biodegradability proves developed blends fully biodegradable, achieving complete disintegration after 49 days. It observed enhanced rate

Recent Approaches to the Plasticization of Poly(lactic Acid) (PLA) (A Review)

Polymers, Год журнала: 2023, Номер 16(1), С. 87 - 87

Опубликована: Дек. 27, 2023

Poly(lactic acid) (PLA) is a polyester attracting growing interest every year in different application fields, such as packaging, cosmetics, food, medicine, etc. Despite its significant advantages, it has low elasticity that may hinder further development and corresponding rise volume of consumption. This review opens discussion basic approaches to PLA plasticization. These considerations include copolymerization blending with flexible polymers, introducing oligomers low-molecular additives, well structural modification. It was demonstrated each approach simplicity cost, but disadvantages, including complex processing the need for additional reagents. According analysis approaches, concluded optimal option copolymers additives obtained via reactive mixing blends other polymers.
