Summary: A UV-curable sealant based on hyperbranched polyester with tunable mechanical properties was developed, showing strong adhesion with tissues and a shear adhesive strength higher than fibrin glue. The biocompatibility of the sealant was assessed by co-culturing it with mouse mesenchymal stem cells for 7 days, with no negative effects on cell viability. This sealant with a tunable elastic modulus has potential for treating wounds with different elastic moduli.

Summary: Through the synthesis of a series of WHPC films with different molecular weights, acrylate group contents, and ion group contents, the influences of these factors on performances were explored. Higher ion group content and lower molecular weight result in smaller particle size, while ion group content has a positive effect on solubility. Smaller molecular weight and particle size lead to lower viscosity, and increasing acrylate group content enhances the double bond final conversion.

Summary: This study investigated an environmentally-friendly synthesis method for bio-based polyester acrylate, which is useful for UV-curable coatings. Itaconic acid and ethoxylated diglycerol were used as bio-based moieties. Although the radical copolymerizability of itaconoyl groups with acryloyl groups has not been fully proven, it is expected that introducing itaconoyl groups into polymer side chains would enhance the cross-linking density. On the other hand, ethoxylated diglyceryl moieties contribute to rapid UV-curing and yield cross-linked polymer due to their multifunctionalities. The manufacturing process in this study resulted in less wastewater discharge and allowed the conversion of the neutralized aqueous layer into a waterborne coating.

Summary: The molecular weight of PDMS affects the chemorheology and viscoelastic behavior of Si-WUPAs. High molecular weight PDMS leads to pseudoplastic behavior, while low molecular weight PDMS exhibits Newtonian behavior. The curing process of Si-WUPAs involves three steps under the influence of a photoinitiator, with increased PDMS molecular weight resulting in longer drying time and higher gelation points. The thermomechanical properties of UV-cured Si-WUPAs films show differences based on the molecular weight of PDMS, with higher molecular weight leading to increased incompatibility and non-uniformity due to micro-phase separation of PDMS chains.
