Degradation Behavior of Rice Husk Fiber‐Reinforced PLA/PBAT Composites in Short‐Term Hydrothermal Environment

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: 142(13)

Published: Jan. 2, 2025

ABSTRACT The rice husk fiber‐reinforced polylactic acid (PLA)/polybutylene adipate terephthalate (PBAT) composites were prepared by using an injection molding technique. An in‐depth investigation into degradation behavior within a short‐term hydrothermal environment, which encompassed multi‐faceted analysis that included surface analysis, process microstructure and structure strength analysis. Results show performance of could be attributed to the weak interfacial adhesion, these defects can seen as observed in electron micrographs. In presence water molecules, it was available bonds susceptible during deformation. Moreover, resultant network from filler‐polymer monitored through functional groups changes, provide insight pattern.

Compatibilization of biopolymer blends: A review

Advanced Industrial and Engineering Polymer Research, Journal Year: 2023, Volume and Issue: 7(4), P. 373 - 404

Published: Nov. 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, Journal Year: 2023, Volume and Issue: 308(7)

Published: Feb. 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
