“…In recent times, there has been a growing interest in sustainable biocomposite products driven by consumer demands and environmental organizations worldwide. − The escalating levels of carbon dioxide (CO 2 ) in the atmosphere pose a substantial threat, necessitating the urgent utilization of biobased natural resources as alternatives to CO 2 -emitting sources. − Despite the wide-ranging applications of polymeric materials, discontinuing the production of plastic materials derived from thermoplastic, thermosetting polymers, and rubber is challenging. − Additionally, composite manufacturing industries heavily rely on petroleum-based resources. , In this context, exploring carbon-based materials sourced from nature presents a viable alternative. − Poly(lactic acid) (PLA) has emerged as a promising and popular bioplastic due to its monomer’s derivation from natural sources like corn, making it a renewable and biodegradable polymer. ,, PLA exhibits higher tensile strength and Young’s modulus compared to synthetic polymer-based plastics, enhancing its competitiveness. − However, it possesses inherent brittleness, heat resistance, and limited crystallization capabilities, hindering its potential applications. − Nevertheless, with suitable physical or chemical modifications, PLA can be considered a carbon-neutral thermoplastic polymer.…”

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.

“…Sodium alginate hydrogels are employed in a wide range of applications [ 1 , 2 , 3 ], especially in biomedical fields such as surgical dressings [ 4 ], drug delivery [ 5 ] and tissue engineering [ 6 ] due to their good biocompatibility, adjustable physicochemical properties, excellent gel formation and water holding properties. Alginate fibrous materials are promising candidates for tissue repair in the biomedical field because of their high surface area, ease of preparation and handling, and their capability to maintain mechanical strength in the wetted state [ 7 , 8 ].…”

In this study, a capillary microfluidic device was constructed, and sodium alginate solution and a pH-sensitive hydrophobic polymer (p(BMA-co-DAMA-co-MMA)) solution were introduced into the device for the preparation of hydrogel fibers loaded with polymer microspheres. The structure of the microsphere fiber, including the size and spacing of the microspheres, could be controlled by flow rate, and the microspheres were able to degrade and release cargo responding to acidic pH conditions. By modification with carboxymethylcellulose (CMC), alginate hydrogel exhibited enhanced pH sensitivity (shrunk in acidic while swollen in basic condition). This led to an impact on the diffusion rate of the molecules released from the inner microspheres. The microsphere fiber showed dramatic and negligible degradation and drug release in tumor cell (i.e., A431 and A549 cells) and normal cell environments, respectively. These results indicated that the microsphere fiber prepared in this study showed selective drug release in acidic environments, such as tumor and inflammation sites, which could be applied as a smart surgical dressing with normal tissue protective properties.
