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). Supporting Information Detailed facts of importance to specialist readers are published as ”Supporting Information”.
