Autonomous Self-healing of Polymeric Gels Cross- Linked by Diarylbibenzofuranone-based Dynamic
نویسندگان
چکیده
Self-healing materials attract a lot of attention because of their ability to repair the internal and external damage, thereby extending the lifetime of the material in numerous applications that we cannot repair easily. Diarylbibenzofuranone (DABBF), which is a novel dynamic covalent bond unit, can reach a state of radically thermodynamic equilibrium under air at room temperature without any stimuli. Furthermore, DABBF and radical species formed from cleaved DABBF are tolerant of oxygen. Here we report that gels cross-linked by DABBF show autonomous selfhealing under air at room temperature.
