Self-healing materials have created a new vision in material science, together with the exploitation which basic chemical and physical principles1-3 display upon healing systems. In particular, the introduction of supramolecular bonds (such as hydrogen-bonds)4 into linear, branched and crosslinked polymers enables multiple SH principles taking into account the relevant timescales of self-healing5. The current presentation addresses principles of self-healing polymers active via supramolecular healing concepts, combining healing principles to obtain multiple healing-cycles together with a the achievement of mechanically stronger material6. Issues of linear-, star- and partially crosslinked supramolecular systems6-8 are addressed, studying the influence of the supramolecular polymers' architecture onto the self-healing properties of the resulting material. Finally, pressure sensitive supramolecular polymers are presented and discussed, where pressure is inducing rupture of supramolecular bonds and in turn generates catalytic activitiy9 able to provide a method to detect stress-detection within solid materials.
