“…In reference to our previous work, 7 2 phr of DCP was applied during compound preparation. To avoid the cellular structure’s damage caused by ADC, 14 2 phr of ADC was chosen, as previously mentioned in the Introduction section. Next, foam fabrication was performed using a Collin P500PM (Collin, Munich, Germany) compression molding machine at 160°C for 10-min heating time and 10-min cooling time at a pressure of 1000 N cm −2 .…”

“…7 -13 However, some researchers reveal that heat release from the exothermic reaction of ADC during the foam process could be an issue due to the low viscosity of linear PBS, cell collapse, and deteriorating mechanical or insulation properties of PBS foams. Yue et al 14 utilized endothermic expandable microspheres (EnEMs) to counteract the exothermic effect from ADC decomposition. With a decrease in the amount of ADC and an increase in EnEMs, the closed-cell fraction of PBS foams is improved from 21% to approximately 100%, the average cell size decreased from 450 µm to 30 µm, the flexural strength increased from 3 MPa to 21 MPa, and the modulus from 106 MPa to 268 MPa.…”

This study examines the effect of poly(butylene adipate- co-terephthalate) (PBAT) content on the physical, morphological, and mechanical properties of poly(butylene succinate) (PBS)/PBAT foam. A compression molding technique was used to prepare the PBS/PBAT foam using the chemical blowing agent azodicarbonamide and the cross-linking agent dicumyl peroxide. The chemical structure and morphological properties of PBS/PBAT foam were examined via Fourier transform infrared and scanning electron microscopy techniques, respectively, whereas tensile and flexural properties were investigated using a universal testing machine. The results reveal that the incorporation of PBAT barely enhances the viscosity of the PBS/PBAT blend, producing only minor changes in the average cell size of PBS/PBAT foam. However, increasing the PBAT content contributes to a relatively significant improvement in the flexibility and toughness of PBS/PBAT foam, where a decrease in Young’s modulus and tensile strength of the PBS/PBAT foam is observed compared with those of the PBS foam. Similar behavior to the tensile results is noticed for the flexural properties of the neat and PBS/PBAT foams.

“…One method is preparing biodegradable polymer foams such as poly(butylene succinate) (PBS) foam, bio-based PU foam, polycaprolactone (PCL) foam, and poly(lactic acid) (PLA) foam [115,116,117,118,119,120,121]. Yue et al [115] prepared sustainable PBS foams invoking a heat-counteracted strategy. The closed cell fraction of PBS foams increased from 21% to 99% with the increase in the endothermic expandable microsphere (EnEMs)/AC loading ratio, as shown in Figure 9.…”

Polymer foams have low density, good heat insulation, good sound insulation effects, high specific strength, and high corrosion resistance, and are widely used in civil and industrial applications. In this paper, the classification of polymer foams, principles of the foaming process, types of blowing agents, and raw materials of polymer foams are reviewed. The research progress of various foaming methods and the current problems and possible solutions are discussed in detail.

“…Among these bio‐based polymers, poly(butylene succinate) (PBS) has been paid great attention due to the comprehensive properties comparable with polypropylene (PP) or polyethylene (PE) 3 . To adapt to the demands of reduction in resource consumption and lightweight, PBS foams with high‐closed‐cell fraction, excellent thermal insulation, and flexural performance have been prepared in our previous study 4 . Similar to other bio‐based polymer foams, enhancement on flame retardancy of PBS foams is still an urgency to broaden its application 5,6 .…”

Sustainable development strategy has aroused a great interest in biomass resources as alternative raw materials. A kind of biomass‐derived poly(butylene succinate) (PBS), has been developed as porous foams to reduce resource exhaustion and meet lightweight demands. For fire‐safety in‐service, graphene oxide (GO) was functionalized by 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) to combine flame‐retardant elements and heat‐barrier function. Hence, a very low loading level of P‐containing GO as only 5 wt% could reduce peak heat release rate (pHRR) and total heat release (THR) of PBS‐based foams by 58.5% and 22.3%, respectively. Meanwhile, N‐/P‐doped mesoporous char with a specific surface area of 136 m2/g, which derived from combustion of flame‐retardant foaming PBS, contributes to a potential of energy storage applications in the capacitor or the anode of Li‐ion battery with long‐term stability. Overall, the sustainability of bio‐based polyester could integrate lightweight of foaming, and be extended to utilization after use via facile combustion inspired by flame‐retardancy design.
