Self-Healing of Chemical Gels Cross-Linked by Diarylbibenzofuranone-Based Trigger-Free Dynamic Covalent Bonds at Room Temperature

Self-Healing of Chemical Gels Cross-Linked by Diarylbibenzofuranone-Based Trigger-Free Dynamic Covalent Bonds at Room Temperature

Linked: Polymers cross‐linked with diarylbibenzofuranone units have been prepared by polyaddition. The exchange of bonds of the gels and their macroscopic self‐healing were accomplished under air at room temperature in the dark. The macroscopic fusion of completely separated parts was successful (se...

Zusammenfassung:Linked: Polymers cross‐linked with diarylbibenzofuranone units have been prepared by polyaddition. The exchange of bonds of the gels and their macroscopic self‐healing were accomplished under air at room temperature in the dark. The macroscopic fusion of completely separated parts was successful (see picture).
