Summary: Poly(lactic acid) (PLA) was toughened by incorporating ductile biodegradable poly(butylene succinate) (PBS) and biobased epoxidized soybean oil (ESO). The addition of a reactive reagent (Joncryl ADR 4370 S) enabled the formation of graft copolymers in situ, resulting in significantly improved compatibility and mechanical properties of the bio-blends. The study utilized various characterization techniques to investigate the compatibility, rheology, crystallization, mechanical properties, and microstructures of the bio-blends. The biodegradable and biobased supertough PLA/PBS/ESO blends exhibited excellent tensile strain at break and impact strength, attributed to the combination of ESO and 4370S.

Summary: This study aimed to improve the low intrinsic ductility of poly (lactic acid) (PLA) by using a novel bio-sourced plasticizer, resulting in a fully biodegradable material suitable for film manufacturing. The addition of epoxidized sunflower oil (ESO) at 6.5% in a 20wt% PLA blend was found to be an effective plasticizer, increasing elongation and enhancing thermal stability. The plasticizers decreased tensile strength and modulus of PLA, while increasing elongation at break.

Summary: Poly (lactic acid) (PLA)/flax fiber/cardanol (or epoxidized cardanol) blends were prepared by mould injection. Epoxidized cardanol effectively improved the toughness of PLA/flax fiber blends. The maximum notched Izod impact strength of PLA/flax fiber/epoxidized cardanol (80/10/10) blend reached 10.42 +/- 0.61 kJ/m2, which was double that of PLA/flax fiber (90/10) blend (5.18 +/- 0.23 kJ/m2). Moreover, the elongation at break of PLA/flax fiber/epoxidized cardanol (85/5/10) blend was promoted to 43.76 +/- 8.58 %, over four times higher than PLA/flax fiber (95/5) blend (9.94 +/- 1.65 %). The improved interfacial compatibility attributed to epoxidized cardanol was responsible for the enhanced toughness.

Summary: Blending of polymers can improve the performance of plastics and expand their application fields. By blending poly(lactic acid) (PLA) with poly(butylene adipate terephthalate) (PBAT), the brittleness of PLA can be addressed. However, the immiscibility of these two polymers limits the properties of the blend. This study explored the use of electron-beam treatment with a compatibilizing agent to improve compatibility and found significant enhancements in mechanical and thermal properties.

Summary: To overcome the limitations of polylactide (PLA) in terms of melt strength, processability, and brittleness, researchers have developed PLA covalent adaptive networks (CANs) with biobased epoxidized soybean oil (ESO) as dynamic crosslinks. By incorporating maleic anhydride (MA) and using Zn2+-catalyzed transesterification exchange, PLA CANs with enhanced melt strength and toughness were successfully produced. The resulting PLA CAN films show promising properties, including high elongation at break and lower environmental impacts compared to petroleum-based plastic films.

Summary: This study investigated the degradation kinetics of epoxidized soybean oil (ESO), finding two main regions in the weight loss plots during thermogravimetry. The weight loss plots, however, exhibited three or more events depending on the composition and experimental parameters. The addition of methyl tetrahydrophthalic anhydride (MTHPA) decreased the activation energy (AE) for curing while increasing the AE during degradation. Friedman's isoconversional model showed proper R-2 for curing kinetics but lower R-2 values for lower anhydride contents during degradation kinetics analysis. The Kissinger-Akahira-Sunose (KAS) and Ozawa-Flynn-Wall (OFW) models had the best R-2 for kinetics evaluation, and the degradation mechanisms fitted reasonably with Avrami-Erofeev (A(n)) and nth-order autocatalytic (C-n) during the first and second weight loss regions. Microstructural analysis suggested two possible pathways for the thermal degradation mechanism of ESO.

Summary: Accurately predicting sea surface temperature is crucial for studying marine ecosystems and global climate. To address the limitations of existing methods in modeling dynamic spatial correlations, we propose a global spatiotemporal graph attention network (GSTGAT) that combines graph neural networks (GNNs). Our network captures global dynamic spatial correlations through a global graph attention network module and utilizes a gated temporal convolutional network module to capture nonlinear temporal correlations. Experimental results on datasets from the Bohai Sea and the South China Sea demonstrate the superior performance of GSTGAT compared to other methods for different prediction horizons.
