“…This property may also benefit chain entanglement. [50,61] The nonisothermal crystallization kinetics analysis was carried out using the Avrami model [64][65][66][67][68] to evaluate the crystalline behaviors of the copolymers under specific thermal conditions, and the calculation method is introduced in the supporting information.

“…In our other work, we found that introducing a small amount of the crosslinking agent benefits the crystallizability of the copolymer owing to the nucleation effect. [66] The crystallizability decreased as the added content increased due to the chain mobility limitation. However, it is challenging to clarify the root cause of the improvement in the crystallization rate.…”

This article reports a potential high-value reuse pathway for a depolymerized vitrimer matrix from abandoned composites. A series of polyethylene terephthalate (PET)-based copolymers containing various amounts of added vitrimer as the toughness modifier were synthesized by melt polymerization. The thermal, mechanical, and crystallization behaviors of the synthesized copolymers were determined, indicating all samples presented excellent thermal stability at Td−5% above 390 ℃. The differential scanning calorimetry and wide-angle X-ray scattering diffraction results demonstrated that the copolymers maintained the crystallization characteristics of normal PET, while a slight reduction in the crystallizability was observed upon the incorporation of the vitrimer. Moreover, the mechanical behaviors of the copolymers were investigated systematically. Surprisingly, a significant increment was observed in the elongation rate from 11.1 to 804.2% when the added vitrimer content increased from 0 to 0.25 wt%, and this trend decreased slightly as the vitrimer content increased further. Impact strength examinations revealed twofold enhancement as the vitrimer concentration increased from 0 to 0.25 wt%, with further improvement as the content was increased. The shore D hardness test illustrated that all samples showed comparable values at around 80, suggesting that introducing the vitrimer does not decrease the hardness of the PET-based copolymers.

Thermoplastic Starch with Poly(butylene adipate-co-terephthalate) Blends Foamed by Supercritical Carbon Dioxide

Starch-based biodegradable foams with a high starch content are developed using industrial starch as the base material and supercritical CO2 as blowing or foaming agents. The superior cushioning properties of these foams can lead to competitiveness in the market. Despite this, a weak melting strength property of starch is not sufficient to hold the foaming agents within it. Due to the rapid diffusion of foaming gas into the environment, it is difficult for starch to maintain pore structure in starch foams. Therefore, producing starch foam by using supercritical CO2 foaming gas faces severe challenges. To overcome this, we have synthesized thermoplastic starch (TPS) by dispersing starch into water or glycerin. Consecutively, the TPS surface was modified by compatibilizer silane A (SA) to improve the dispersion with poly(butylene adipate-co-terephthalate) (PBAT) to become (TPS with SA)/PBAT composite foam. Furthermore, the foam-forming process was optimized by varying the ratios of TPS and PBAT under different forming temperatures of 85 °C to 105 °C, and two different pressures, 17 Mpa and 23 Mpa were studied in detail. The obtained results indicate that the SA surface modification on TPS can influence the great compatibility with PBAT blended foams (foam density: 0.16 g/cm3); whereas unmodified TPS and PBAT (foam density: 0.349 g/cm3) exhibit high foam density, rigid foam structure, and poor tensile properties. In addition, we have found that the 80% TPS/20% PBAT foam can be achieved with good flexible properties. Because of this flexibility, lightweight and environment-friendly nature, we have the opportunity to resolve the strong demands from the packing market.
