“…Mitigating these issues necessitates a range of techniques, including reactive blending, copolymerization, and modifying polymer chains chemically or physically to enhance compatibility and intermolecular interactions between the polymers. 1,[4][5][6] A commonly employed approach is the addition of reactive compatibilizers, such as lysine triisocyanate, 7 benzoyl peroxide, 8 and ethylene-methyl acrylate-glycidyl methacrylate random terpolymer, 9,10 and so on, which bolster interfacial adhesion between the polymers, facilitating improved blending and overall material quality. Furthermore, the low gas barrier property of these polymers constitutes a critical challenge, especially in their application in food packaging.…”

This study focuses on developing compostable nanocomposite blown films, aiming to enhance oxygen barrier properties while maintaining good mechanical performance. Polybutylene succinate (PBS) and its blend with polylactic acid (PLA) were selected as matrices for the films. Organo‐montmorillonite Delite®43B (D43B) clay was incorporated to improve oxygen barrier, and random ethylene‐methyl acrylate‐glycidyl methacrylate terpolymer served as a plasticizer and reactive compatibilizer. Different blending sequences were examined to determine the optimal one that led to significant enhancements in both the barrier and mechanical properties of the final nanocomposite blown film. Various techniques, including SEM, TEM, XRD, DSC, oxygen permeability, and tensile testing were employed to characterize the morphology of the compounds and blown films. The results reveal greater oxygen barrier properties depending on the blending sequence. Indeed, a reduction in oxygen permeability exceeding 50% was observed following the addition of 3 wt% of D43B to the PBS/PLA film, selectively localized in the PLA phase. This enhancement further intensified after the addition of 5 wt% of the epoxy functionalized compatibilizer.Highlights Enhancing PLA‐PBS compatibility with the epoxy functionalized compatibilizer led to a reduction in the final film's oxygen permeability. Achieving ideal ductility and barrier balance in films requires a synergistic blend of components: D43B, PLA, PBS, and compatibilizer. Optimizing balanced synergistic effects among compounds depends on the blending sequence method.

In this study, equimolar amounts of poly(l‐lactic acid) (PLLA) and poly(d‐lactide acid) (PDLA) were melt‐blended with PBSA, to obtain a novel and environmentally friendly PBSA/sc‐PLA blend, through in situ formation of stereo‐complex poly(lactic acid) (sc‐PLA). Differential scanning calorimetry and wide‐angle X‐ray diffractometry confirmed the formation of sc‐PLA in PBSA matrix. The sc‐PLA was uniformly dispersed in PBSA matrix. Up to 20 wt% sc‐PLA concentration, the PBSA/sc‐PLA blends showed solid‐like flow behavior in the low‐frequency region. Moreover, sc‐PLA could reinforce the PBSA matrix. The Young's modulus, yield strength, and storage modulus of PBSA/sc‐PLA blend increased with increase in sc‐PLA content. In addition, the heat deflection temperatures of PBSA/sc‐PLA blends increased on incorporation of sc‐PLA, thus enhancing the heat resistance. Compared with neat PBSA, the hydrolytic degradation of PBSA/sc‐PLA blends was improved. This work provides an effective strategy to obtain high performance PBSA materials and expand the application scope of PBSA.

Wood Residue-Derived Biochar as a Low-Cost, Lubricating Filler in Poly(butylene succinate-co-adipate) Biocomposites

This study focused on the development of a novel biocomposite material formed by a thermoplastic biodegradable polyester, poly(butylene succinate-co-adipate) (PBSA), and a carbonaceous filler as biochar (BC) derived by the pyrolysis of woody biomass waste. Composites with various BC contents (5, 10, 15, and 20 wt.%) were obtained by melt extrusion and investigated in terms of their processability, thermal, rheological, and mechanical properties. In all the composites, BC lowered melt viscosity, behaving as a lubricant, and enhancing composite extrudability and injection moulding at high temperatures up to 20 wt.% of biochar. While the use of biochar did not significantly change composite thermal stability, it increased its stiffness (Young modulus). Differential scanning calorimeter (DSC) revealed the presence of a second crystal phase induced by the filler addition. Furthermore, results suggest that biochar may form a particle network that hinders polymer chain disentanglement, reducing polymer flexibility. A biochar content of 10 wt.% was selected as the best trade-off concentration to improve the composite processability and cost competitiveness without compromising excessively the tensile properties. The findings support the use of biochar as a sustainable renewable filler and pigment for PBSA. Biochar is a suitable candidate to replace more traditional carbon black pigments for the production of biodegradable and inexpensive innovative PBSA composites with potential fertilizing properties to be used in agricultural applications.
