A study of the temperature dependent healing capabilities of new polymers based on Diels-Alder cycloaddition

Because of its thermal reversibility, the retro-Diels-Alder (RDA) reaction represents an appealing possibility to produce self-healing polymers with well-defined architectures and tunable properties [1]. However, the polymer architecture for which the Diels-Alder (DA) reaction can best be used to contribute to the healing process is still not...

Self-healing metallopolymers: Detailed inverstigation of the self-healing properties by scratch testing

In the last decade several intrinsic self-healing materials have been developed in which the healing mechanism was mainly based on the reversibility of a certain structural element. For this purpose, reversible covalent bonds, e.g., based on the Diels-Alder reaction or weaker non-covalent interactions, e.g., hydrogen bonding, ionic interactions...

Metallopolymers as self-healing materials

Metallopolymers represent an interesting class of supramolecular polymers. Their properties can be tuned by the selection of the attached/incorporated ligand as well as the choice of the corresponding metal ion.[1] In this manner, also reversible interactions, i.e. on the one side undirected ionic interactions between positively charged metal...

One-component intrinsic self-healing polymer for coatings based on reversible crosslinking by Diels-Alder-cycloadditions

Self-healing can be achieved in polymer coatings by the incorporation of extrinsic materials, i.e. a healing agent is embedded into the coating (e.g., within capsules). In contrast the polymeric coating itself can feature the ability for healing – for instance if reversible covalent bonds are introduced into the polymer network. The Diels-.Alder...

Contributions of hard and soft blocks in the self-healing of metal-ligand-containing block copolymers

The main aim of this work is to study the respective contribution of the hard and soft blocks of a metal-ligand containing block copolymer to the self-healing behavior. To this aim, different block copolymers containing terpyridine were synthesized using reversible addition-fragmentation chain transfer (RAFT) polymerization. These block...
