Summary: Plastics are commonly used in packaging due to their strong mechanical and barrier properties. However, their lack of biodegradability poses significant environmental threats. Cellulose, with its strong and stiff molecular structure, biocompatibility, biodegradability, low toxicity, and abundance, is a promising alternative. This study investigates the effect of plasticizers glycerol and sorbitol on the properties of cellulose films, revealing that the addition of plasticizers improves tensile strength and elongation at break. These findings contribute to the development of novel biodegradable packaging films based on cellulose and the reduction of plastic pollution.

Summary: Plasticizer-assisted interfacial polymerization was used to develop TFC reverse osmosis membranes with improved water permeability and comparable salt selectivity. The introduction of plasticizers disrupted original amide-amide bonding between polyamide chains, converting the polyamide structure from stiff to flexible, significantly promoting water diffusion efficiency.

Summary: The study demonstrates the feasibility of using plasticizer-assisted interfacial polymerization to fabricate aromatic polyamide layers with improved desalination performance. By adjusting the concentration of plasticizer, water flux can be significantly enhanced while salt rejection may slightly decrease. The introduction of DEP disrupts the hydrogen bonding between polyamide chains, enhancing the softness of the polyamide layer and promoting water diffusion efficiency.

Summary: Edible films made from basil seed gum (BSG) with different gum and plasticizer concentrations were studied. The films exhibited good barrier properties and thermal stability. Increasing the gum and glycerol concentrations improved film crystallinity and barrier properties. Films with low gum and high glycerol ratio had smooth surfaces and suitable transparency for packaging. Higher glycerol and BSG concentrations led to increased water vapor permeability. The complete dissolution of the film in soil suggested its eco-friendly nature. BSG-based films with appropriate gum and plasticizer concentrations can be a low-cost, edible, and biodegradable packaging material for foods, with excellent barrier, thermal, and structural properties.

Summary: On-demand biodegradable superhydrophilic membranes were developed for ultrafast purification of oily water. The use of polyethylene oxide hydrogels increased the hydrogen bonds formed between the membrane surface and water molecules by 357.6%, converting hydrophobic membranes into superhydrophilic ones. The newly designed nanofiber membranes exhibited a significant increase in oil-in-water emulsion permeance and separation efficiency, outperforming state-of-the-art membranes.

Summary: Colorimetric indicators with different molar concentrations of plasticizers exhibit visible color changes in response to pH variations or exposure to ammonia vapors, indicating microbial spoilage in shrimp. The immobilization of plasticizers in polymer matrices is confirmed through spectroscopy and microscopy techniques. These indicators are simple, effective, and environmentally friendly alternatives to existing chemical sensors.

Summary: Polyelectrolyte multilayers (PEMMs) are versatile materials for nanofiltration membranes, but their nonrenewable nature raises sustainability concerns. This study proposes lignin as a renewable and biodegradable alternative for PEMM fabrication. Experimental results demonstrate that lignin can effectively replace fossil-based polyelectrolytes, producing PEMMs with excellent nanofiltration properties and stability.

Summary: The study revealed differences in properties and effects of the plasticizers, 2NPOE and TBEP, in PIMs design. Compared to TBEP, 2NPOE showed lower dispersion and affinity in PIMs, but had a stronger plasticizing effect at higher content, leading to increased membrane permeability; however, due to lower affinity among components, stability decreased in 2NPOE-PIMs.

Summary: The use of non-biodegradable plastic is a major global environmental issue. Therefore, the use of biodegradable microbial polymers, such as levan and gellan gum, is desirable for developing sustainable packaging films for the food industry. This study successfully developed polymer films using different concentrations of levan and gellan gum, along with glycerol and citric acid. The film with optimal composition showed improved stability, transparency, and elongation at break compared to films made solely from gellan gum. Characterization analysis demonstrated the thermal stability and potential applications of the levan-gellan gum film in the food industry.

Summary: In this study, a biodegradable plasticizer called CEPT was synthesized from cardanol via acid-free catalysis. The polyvinyl chloride plasticized with CEPT exhibited good mechanical properties, thermal degradation, thermal aging properties, and solvent extraction resistance. It was found that CEPT underwent biodegradation and produced small-molecular components in active soil and in the Tenebrio molitor digestive system.

Summary: Lactide-valerolactone copolymers have potential application in the packaging sector. Different copolymers were synthesized and their reaction kinetics and microstructure were analyzed. Lactide showed higher reactivity than valerolactone, resulting in composition drift during the reaction. The thermal, mechanical, and barrier properties of the copolymers were also studied. The incorporation of valerolactone resulted in copolymers with higher ductility and intermediate water and oxygen permeability, making them suitable materials for packaging.

Summary: In this study, copolymers of lactide and ethylene brassylate were successfully synthesized for the development of polymeric scaffolds for soft tissue regeneration. These copolymers demonstrated adjustable mechanical properties, thermoplasticity, and cytocompatibility. The addition of nanofillers allowed further modulation of their mechanical properties. Nanostructured scaffolds were fabricated through thermo-pressing, providing geometrical cues for cell adhesion and elongation.
