“…The blend's composition, processing circumstances, rheological properties, and interfacial tension of the two elements all affect how a two-phase system evolves morphologically [213][214][215][216]. By adjusting the ratio of PLA to the rubbery polymer, several morphologies (droplet, co-continuous or double emulsion) may be produced, allowing the mechanical performance of the finished product to be managed [217][218][219]. In the work of Ojijo et al [194] different blends of PLA/PBSA (100/0, 90/10, 70/30, 60/40, 50/50, 40/60, 30/70, 10/90, 0/100) were prepared and Fourier-transform infrared (FTIR) spectroscopy allowed them to assess the phase separation resulting from the absence of any significant interaction between the two components.…”

Biopolymers obtained from renewable resources are an interesting alternative to conventional polymers obtained from fossil resources, as they are sustainable and environmentally friendly. Poly(lactic acid) (PLA) is a biodegradable aliphatic polyester produced from 100% renewable plant resources and plays a key role in the biopolymer market, and is experiencing ever-increasing use worldwide. Unfortunately, this biopolymer has some usage limitations when compared with traditional polymers; therefore, blending it with other biopolymers, such as poly(butylene succinate) (PBS), poly(butylene succinate-co-butylene adipate) (PBSA), poly(butylene adipate-co-butylene terephthalate) (PBAT) and different poly(hydroxyalkanoates) (PHA), is considered an interesting method to improve it significantly, customize its properties and extend the range of its applications. The following review highlights, in its first part, the physico-chemical and mechanical properties of PLA in comparison to the other biopolymers listed above, highlighting the various drawbacks of PLA. The second part of the review deals with recent developments, results, and perspectives in the field of PLA-based blends.

“…Puekpoonpoal et al observed an improvement in blown extrusion when PBS is introduced in a PBSA matrix as secondary phase and can be furtherly enhanced when PLA is used as well. 36 This paper wants to study the possibility of producing binary blends of PBSA and PHBH suitable for thermoforming, where PBSA is the main polymeric phase. In this way, the interesting properties of PBSA, such as the good mechanical behavior and its high biodegradation rate, can be fully exploited.…”

Thermoformed fossil‐based disposable packaging is widely used in everyday life but it represents a serious environmental problem, as it is often incorrectly dispersed or destined to landfills. Bio‐based and biodegradable materials can constitute and effective solution to this issue. Two different blends of poly(butylene succinate‐co‐butylene adipate) (PBSA) and Poly (3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH) were studied as constituents for disposable packaging production. The blends were produced via twin screw extrusion. Sheets were cast extruded and then thermoformed into trays. A rheological, thermal and mechanical characterization was performed on compounds and manufacts. Both blends presented a good processability and interesting properties for packaging application, which can be tailored by varying the percentage of constituent polymers.

“…Figure11showed the SEM images of fracture surfaces form the composites with different blend ratios. The smooth fracture surface of PLA (Figure11A) showed distinctly characteristic of brittle materials 45,46. Compared with PLA, the morphology of PLA/POE-(GMA-NAg) 50 -20 (Figure11B) exhibited a rougher fracture surface, in which a typical sea-island structure was observed.…”

Thermoplastic elastomer ethylene/α-octene co-polymer (POE) is a special polymer material with both elasticity and thermoplasticity. However, the nonpolarity and lowtensile strength of POE limit its application in polar materials and high-strength materials fields. In this study, we synthesized a specific molecule with C═C bonds and N H bonds, which was introduced into POE to construct hydrogen bonding network, and the prepared modified POE is further blended with carboxyl terminated polystyrene nanospheres as toughening agent to prepare modified POE elastomer composites. Based on such dual toughening strategy containing chemical modification and physical toughening, the modified POE elastomer composites possess improved mechanical properties. The composites achieve a tensile strength of 21.4 MPa, elongation at break of 1268%, fracture energy of 109.6 MJÁm À3 and exhibit improved thermal stability. Impressively, the tensile strength of reprocessed composites is restored to more than 90% of their original tensile strength even after four times of reprocessing steps, demonstrating excellent reusability.
