ABSTRACT The photo‐induced cis‐trans isomerization of azobenzene molecules, known for their significant color changes, is extensively utilized in the functional modification polymeric materials. However, research on functionalization biomass‐based polyesters with limited. A key raw material coatings possess reactive double bonds and excellent film‐forming capabilities, offering advantages polyester applications. In this study, AESO served as matrix acrylate derivatives molecules. Under ultraviolet radiation, underwent a carbon–carbon crosslinking reaction to synthesize novel resin. coating resin PET substrate exhibited pencil hardness (3B), adhesion (5B), solvent resistance. By alternating exposure blue light, displayed reversible switching between cis trans isomers, enabling writing erasing patterns. Even after 20 cycles erasing, high‐resolution patterns could still be observed (clearly visible under 12x microscope). Furthermore, image retained up 2 h sunlight irradiation. This study presents new method functionalizing biobased polyesters.

The development of effective wound dressings is critical for enhancing patient outcomes in both acute and chronic care scenarios. In this research, electrospun nanofibrous scaffolds were fabricated from poly(ε-caprolactone) (PCL), enhanced with curcumin reduced graphene oxide (RGO) to optimize their biomedical applications, particularly healing. resulting rigorously characterized through scanning electron microscopy, contact angle measurements, water uptake capacity, vapor transmission rate assays. biocompatibility these novel nanofibers was affirmed MTT Antibacterial tests confirmed the scaffolds' ability inhibit Gram-negative Gram-positive bacteria, inhibition zones measuring up 9.9 mm S. aureus 9.2 E. coli. Additionally, containing exhibited significant antioxidant activity, achieving 40% radical scavenging efficiency. study further revealed capability sustained drug release, an initial burst release within first 12 hours followed by a gradual over 168 hours. Overall, PCL-curcumin-RGO mats demonstrated considerable potential notably field dressings, due antibacterial, antioxidant, biocompatible properties.

Abstract This study investigates the development and characterization of UV‐curable Poly(ε‐caprolactone) (PCL), Acrylated Epoxidized Soybean Oil (AESO), Carbon Nanotubes (CNT) nanocomposites for biomedical engineering applications. The PCL/AESO blends were prepared in various ratios, CNTs incorporated at concentrations 0.5, 1.0, 1.5 wt% to enhance mechanical properties. formulations aimed leverage rapid curing times, precise control over material properties, ability fabricate complex structures. Results indicated that incorporation improved tensile strength, modulus, toughness composites. PCL/AESO/CNT exhibited a strength increase 25%, modulus improvement 30%, enhancement 20% compared pure PCL. Thermal analysis showed an crystallization temperature thermal stability, with crystallinity degree 63.31% maximum degradation 407°C B/C 50/50/1.5 sample. Biocompatibility assessments using L929 fibroblast cells revealed composites supported cell viability proliferation 7 days negligible cytotoxicity. Cell attachment studies favorable morphology adherence, suggesting conducive environment growth differentiation. Hydrolytic biodegradation demonstrated adjustable rates, making these suitable applications requiring controlled biodegradation.

In the field of regenerative medicine, acrylated epoxidized vegetable oils are emerging as a promising avenue exploration. The aim this study is to evaluate degradability two formulations soybean oil (AESO): pure AESO and diluted with (SO) for potential bioprintability applications. comprehensive investigation these polymeric included optimization polymerization conditions, confirmation cytocompatibility, and, most importantly, their degradability. results reveal that AESO, used biomaterial biomedical applications, undergoes distinctive degradation process, combining both enzymatic oxidative (AESO/SO samples lose 29.45% weight after 60 days). This phenomenon result complex interplay factors, including chemical composition physical characteristics polymer, unique tissue environment in which it implanted, duration implantation.
