Composites of synthetic bone mineral substitutes (BMS) and biodegradable polyesters are of particular interest for bone surgery and orthopedics. Manufacturing of composite scaffolds commonly uses mixing of the BMS with polymer melts. Melt processing requires a high homogeneity of the mixing, and is complicated by BMS-promoted thermal degradation of polymers. In our work, poly(L-lactide) (PLLA) and poly(ε-caprolactone) (PCL) composites reinforced by commercial β-tricalcium phosphate (βTCP) or synthesized carbonated hydroxyapatite with hexagonal and plate-like crystallite shapes (hCAp and pCAp, respectively) were fabricated using injection molding. pCAp-based composites showed advanced mechanical and thermal characteristics, and the best set of mechanical characteristics was observed for the PLLA-based composite containing 25 wt% of pCAp. To achieve compatibility of polyesters and pCAp, reactive block copolymers of PLLA or PCL with poly(tert-butyl ethylene phosphate) (C1 and C2, respectively) were introduced to the composite. The formation of a polyester-b-poly(ethylene phosphoric acid) (PEPA) compatibilizer during composite preparation, followed by chemical binding of PEPA with pCAp, have been proved experimentally. The presence of 5 wt% of the compatibilizer provided deeper homogenization of the composite, resulting in a marked increase in strength and moduli as well as a more pronounced nucleation effect during isothermal crystallization. The use of C1 increased the thermal stability of the PLLA-based composite, containing 25 wt% of pCAp. In view of positive impacts of polyester-b-PEPA on composite homogeneity, mechanical characteristics, and thermal stability, polyester-b-PEPA will find application in the further development of composite materials for bone surgery and orthopedics.

“…In a previous study, we used poly(butylene 2,5-furan dicarboxylate) (PBF) for blending with PLA and observed improved toughening without significant deterioration . Moreover, by incorporating compatibilizers, such as reactive or reactive extrusion modifiers, the interfacial adhesion between PPF and PLA can be improved, leading to enhanced compatibility and potentially influencing the mechanical and thermal properties of the blends. − The presence of biobased plasticizers enhances the hydrophilicity of PLA, increases the microbial accessibility, and accelerates its breakdown in natural environments. These findings underscore the significance of biobased plasticizers in modifying the biodegradability properties of PLA and improving its overall sustainability. , The investigation of these interfacial interactions can provide valuable insights into the performance and potential applications of PPF/PLA blends.…”

Sustainable polymeric blends were successfully produced by blending biobased poly(propylene 2,5-furan dicarboxylate) (PPF) with poly(lactic acid) (PLA). This study aimed to enhance the toughness of PLA, which is known for its inherent brittleness, by incorporating compatible polymeric additives. In this regard, a biosynthesized PPF polymer was used to strengthen PLA, resulting in improved tensile properties and the potential for biodegradability, as both PLA and PPF are derived from natural sources. The study revealed that the highest tensile strength (89.46 ± 2.98 MPa) was achieved with a 30% PPF reinforcement of PLA, while the greatest elongation at break (63.85 ± 4.10%) was observed with a 20% PPF reinforcement, compared to neat PLA. Additionally, the 30% PPF reinforcement of PLA exhibited a significantly higher Young's modulus of 3197.35 ± 107.25 MPa. All the blends displayed superior tensile strengths and elongation at break compared to neat PLA. Tensile strengths showed an increasing trend with a higher content of PPF copolymers. Morphological investigations indicated limited compatibility between PLA and PPF, but this characteristic did not negatively impact the thermo-mechanical performance of the developed blends. Furthermore, the thermal stability of the blends increased with a higher loading of PPF in the polymeric blend system. Overall, these sustainable composite products demonstrate promising potential for applications requiring enhanced mechanical and thermal properties. The results suggest that the developed blends are suitable for scalable production and real-life applications.

“…To the best of our knowledge, reviews in this regard are very rare in the literature. Some reviews on the effect of plasticizers are about improving the flexibility of the most common biopolymers such as PLA [ 9 ] and starch [ 10 , 11 ], but there is no dedicated article focusing the effect of plasticizers on alginate-based films, in particular. The objective of this review paper is to investigate the effects of different types of plasticizers on water vapor permeability, and the thermal, mechanical, and physical properties of alginate-based films.…”

In recent years, there has been a growing attempt to manipulate various properties of biodegradable materials to use them as alternatives to their synthetic plastic counterparts. Alginate is a polysaccharide extracted from seaweed or soil bacteria that is considered one of the most promising materials for numerous applications. However, alginate potential for various applications is relatively limited due to brittleness, poor mechanical properties, scaling-up difficulties, and high water vapor permeability (WVP). Choosing an appropriate plasticizer can alleviate the situation by providing higher flexibility, workability, processability, and in some cases, higher hydrophobicity. This review paper discusses the main results and developments regarding the effects of various plasticizers on the properties of alginate-based films during the last decades. The plasticizers used for plasticizing alginate were classified into different categories, and their behavior under different concentrations and conditions was studied. Moreover, the drawback effects of plasticizers on the mechanical properties and WVP of the films are discussed. Finally, the role of plasticizers in the improved processing of alginate and the lack of knowledge on some aspects of plasticized alginate films is clarified, and accordingly, some recommendations for more classical studies of the plasticized alginate films in the future are offered.
