Sustainable composites from biodegradable poly (lactic acid) modified with isosorbide-based plasticizer: Preparation and performance

Journal of Thermoplastic Composite Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Bio-based resin plasticizers not only overcome the toxicity and non-degradability of phthalate plasticizers, but also expand application areas polymers. In this study, environmentally sustainable plasticizer isosorbide dinonanoate (ISN) is chosen to plasticize toughen PLA for enhancing impact strength processability, further expanding in field flexible packaging materials. Our work primarily focuses on strength, crystallinity, glass transition temperature (Tg), morphology composites. The results demonstrate that adding ISN at a concentration 25 phr reduces Tg by 22°C, representing 35.4% decrease relative neat PLA, thus confirming effective plasticizing PLA; Izod arrives 688 J/m, approximately 30-fold increase, demonstrating dramatically enhanced toughness equilibrium torque 1.9 Nm, involving improved processability DSC tests show crystallinity composites improves when amount increases. Notably, increases 248% from 7.07% 24.59% addition phr. Meanwhile, SEM reveals has good compatibility with as evidenced absence phase separation fracture surfaces

Developing a stiffness-toughness balance, low-cost, and biodegradable PLA composite is an effective strategy for improving product market competitiveness, reducing dependence on petroleum-based resources protecting the environment. Rice husk (RH) extensively used as filler in polymers, but addition of too much rice into has damaged toughness composite. In this work, fully composites with balance low cost are successfully fabricated through melt blending PLA, RH acetyl tributyl citrate (ATBC). The results show that bio-based plasticizer ATBC can improve flowability composites, further enhancing their processability, which promotes dispersion PLA. impact strength elongation at break PLAC20 reach value 100 J/m 148%, achieving increase 4.3 60.1 times compared PLAC0, respectively. torque rheological test shows maximum equilibrium arrive 25.3 N/m 2.3 N/m, about 67.4% 63.5% lower than those PLAC0 after incorporation 18 phr ATBC, respectively, indicating significant improvement processing performance. As amount increases, water absorption rate progressively rises, while contact angle steadily diminishes, resulting hydrophilicity, thereby broadening its potential applications.

Abstract Through anionic two‐stage polymerization, block‐type styrene‐butadiene rubber (SSBR) with systematically regulable low‐temperature loss peaks is successfully prepared. The influence of 1,2‐Bd unit in the soft segment SSBR on mechanical properties, dynamic and microscopic morphology studied, while pressure factors are introduced into studies. a containing 21.9 wt% exhibits highest tensile strength, elongation at break, tear strength. Under atmospheric pressure, influences properties by altering chain segment's motion capability. As mass fraction increases from to 58.6 wt%, tan δ max increases, glass transition temperature −59.0 −18.9°C. Additionally, influenced thermodynamic compatibility, transitions strong separation weak separation. Pressure affects free volume segments. reduces , T g raises average 11°C.
