A flexible and controllable is proposed for fabricating long-chain branched polypropylene (LCBPP) foams with high resilience and strength. LCBPP was blended with thermoplastic polyester elastomer (TPEE) using polyethylene octene elastomer grafted glycidyl methacrylate (POE-g-GMA) as a compatibilizer at different mass ratios, and the blends were then used to prepare foams at different temperatures by the supercritical CO 2 batch foaming method. The foams were then tested for their compressive permanent strain and compressive strength. The results showed that introducing TPEE and POE-g-GMA increased the resilience. In particular, the permanent strain of the LCBPP/ TPEE/POE-g-GMA foam at a ratio of 90/10/7 decreased from an initial 14.5% for the original LCBPP foam to 5% after five compression cycles. However, the compressive strength decreased from 65.59 to 39.82 kPa. Therefore, the foam density (ρ) and cell size (d) were adjusted to balance the resilience and strength. Increasing ρ/d from 0.32 to 3.10 increased the compressive strength significantly from 39.82 to 91.67 kPa while the permanent strain only increased 3.5%. Thus, the proposed strategy realized LCBPP foams with high resilience and compressive strength.

“…According to the principle of energy dissipation, the more viscous phases tend to form the droplet morphology and the less viscous phase forms the matrix. 24 In this study, PHBH forms the matrix, while PBSA forms dispersed droplets inside the PHBH. This type of structure results in an increase in physico-mechanical properties compared to a monophasic structure.…”

Progress in design and processing of polyhydroxyalkanoates (PHAs): Home compostable poly(3‐hydroxybutyrate‐co—3‐hydroxyhexanoate) (PHBHHx)/polybutylene succinate‐co‐adipate (PBSA) blend

Polyhydroxyalkanoates (PHA) are biodegradable linear polyesters mainly produced by bacterial fermentation. These materials are biocompatible, non-toxic, and have a low environmental impact, making them an excellent alternative to fossil-based plastics in food packaging. Despite their promising characteristics, PHAs have several disadvantages, such as brittleness, slow nucleation process, thermal instability and consequently poor processability. In this article, poly(3-hydroxybutyrate-co-3-hexanoate) (PHBHx), a copolymer belonging to the class of PHAs, was blended with polybutylene succinate-co-adipate (PBSA) and other process additives in order to improve its properties and realize a hot food container compostable in a domestic environment. The material in the pellet form was produced by reactive extrusion with a corotating twin-screw extruder. The compound was then processed by cast extrusion and the resulting film was thermoformed into a rectangular container. All the semi-finished products were characterized thermo-mechanically and with chemical-physical tests, demonstrating good processability, thermal resistance of 100 C, complete impermeability to oxygen, transmission of light radiation less than 30% and high toughness (<5 kJ/m 2 ). In addition, the morphology of the blende was also investigated by SEM and XRD analysis.compostability, extrusion, poly(butylene succinate-co-adipate) (PBSA), polyhydroxyalkanoates (PHA), polyhydroxybutyrate-co-hexanoate (PHBH), thermoforming molding
