Summary: Conductive rhenium oxide-polytetrahydrofuran (ReOx-PTHF) has high electrical conductivity and self-healing properties, and can be applied to self-repairing electronic circuits. Its self-healing properties and high electrical conductivity prevent severe loss of electrical conductivity in flexible devices. Additionally, it is not swellable and decomposable in aqueous and saltwater environments.

Summary: This study introduces a novel cross-linker, sulfanilic acid (SA), to improve the mechanical performance of hydrogels. SA overcomes the heterogeneity of cross-links in the topological structure of gels and forms multiple hydrogen bonds with poly(acrylamide) (PAM) chains, resulting in a distinct energy dissipation mode. The PAM/SA gel exhibits good self-recoverability and remarkable fatigue resistance.

Summary: The study explored the cross-linking between epoxidized linseed oil (ELO) and suberin to produce fully biobased and nontoxic thermosets. Through polymerization mechanisms investigation and analysis of thermomechanical properties, it was found that the ELO/suberin films have a wide range of relaxation temperature and tunable glass transition temperature depending on the suberin ratio.

Summary: A novel bis(1,3-dioxolan-4-one) monomer was developed from L-(+)-tartaric acid and can be used as a cross-linker to produce cross-linked, degradable polymers. The structure and properties of the polymers can be tuned by the choice and composition of co-monomers, allowing for high performance and adjustable degradation. This research provides a solution for the production of sustainable thermosets with controllable degradability.

Summary: Recent advances in composite hydrogels have shown that incorporating liquid metals (LM) microdroplets can enhance material properties and enable specialized stimuli-responsive functionalities. LM microdroplets can act as initiators for ultra-fast polymerization and also influence the resulting hydrogel material and stimuli-responsive characteristics. Experimental results demonstrate that higher ratios of LM lead to improved stimuli-responsive behaviors, such as swelling and ionic actuation. These biocompatible LM-hydrogel composites open up new opportunities for soft robotics and biomedical applications.

Summary: By utilizing chitosan as a mucoadhesive and pH-sensitive polymer, a novel CS/PVP-co-poly (AMPS) network-based hydrogel was fabricated. Captopril was successfully loaded into the hydrogel network using a diffusion-aided-swelling technique. The physicochemical properties and morphology of the hydrogel were characterized, showing the entrapment of captopril at a molecular level and the dissolution profile of the hydrogel system. The developed hydrogel system demonstrated mucoadhesive properties and biocompatibility, making it suitable for sustained release of captopril and improved drug absorption in the stomach.
