Summary: The COVID-19 pandemic has generated a massive demand for disposable facemasks, resulting in plastic pollution due to the use of nonbiodegradable materials. To address this issue, the study focuses on manufacturing biobased and biodegradable facemasks using melt electrospinning technique. The effects of various parameters on fiber diameter and uniformity are investigated, along with the impact of climate chamber and infrared heater on fiber solidification. The study provides insights into process optimization and highlights the unsuitability of the produced samples as filter materials for medical face masks due to their large pore size.

Summary: Biobased pH indicators were developed using nanofibrous mats made from polylactide and anthocyanin from black carrot, which acted as a natural pH-sensitive colorant. The mats had a high surface area that facilitated the interaction of dye molecules with the surroundings. After treating the mats with pH buffer solutions, significant visible color changes were observed, indicating their potential use in pH detection applications such as food packaging.

Summary: Melt electrospinning is a versatile technique for producing microfibers and sub-microfibers. This study investigated the effect of field polarity on the diameter of melt-electrospun PBS fibers and examined the transferability of these results to a pilot-scale device. Changing the polarity significantly reduced the fiber diameter at both scales, but the fibers stuck together at the laboratory scale. The study offers a low-cost method to decrease the diameter of melt-electrospun PBS fibers and provides insights into the transferability of the technique.

Summary: The Qu/COS/PVA composite nanofiber membranes with excellent antibacterial properties were fabricated using electrospinning technology. The effects of Qu and COS content on solution conductivity, viscosity, and surface tension were investigated. The results showed that increasing COS and Qu content led to thinner fibers and increased conductivity. The antibacterial test demonstrated that the Qu-loaded COS/PVA nanofiber membranes showed significantly enhanced antibacterial properties against Escherichia coli.

Summary: Nanofibers with gelatin and curcumin were produced using electrospinning, and the effects of gelatin concentration and crosslinking with citric acid on the characteristics of the nanofibers were studied. The obtained nanofibers were characterized and it was found that the films with gelatin and curcumin showed improved antioxidant activity and other properties. These films have potential applications in reducing water loss and oxidation in cut fruits for extended shelf lives.

Summary: This study synthesized DNA-cationic surfactant complexes and blended them with a polylactic acid biopolymer to obtain nanofibers, on which copper nanoparticles were synthesized. The nanofibers showed uniform morphology and the copper nanoparticles exhibited uniform growth on them. The incorporation of DNA complexes improved the biocompatibility and antibacterial activity of the nanofibers.

Summary: Curcumin and Fenugreek essential oil were blended into PLA matrix to improve the functional properties of the composite film. The addition of these fillers improved UV-blocking, tensile strength, flexibility, and other properties while slightly decreasing water vapor permeability. The PLA-based composite film also exhibited good antibacterial and anti-oxidant properties, as well as comparable food quality to commercial polyethylene film in a strawberry test.

Summary: This study evaluates the effect of different ratios of quercetin and curcuminoids on antimicrobial, antioxidant, cell migration, and wound healing properties. The results demonstrate that the combination of quercetin and curcuminoids inhibits the growth of S. aureus and P. aeruginosa, has lower antioxidant activity compared to curcuminoids alone, and promotes fibroblast migration and wound closure.

Summary: Manufacturers of technical polymers are increasingly concerned about the degradability of their products due to public interest in greenhouse gas emissions and microplastic pollution. Biobased polymers offer a solution, but they are more expensive and less well characterized than conventional petrochemical polymers. This article compares the performance of polypropylene, a petrochemical polymer, with commercially available biobased polymers and shows the possibility of using home-compostable biopolymers for products with lower mechanical properties.
