Understanding the molecular mechanisms involved in the interfacial self-healing of supramolecular rubbers

Supramolecular rubbers based on 2-aminoethylimidazolidone and fatty acids with epoxy crosslinks have been shown to self-heal via multiple hydrogen bonding sites. In this work, several tools are used to investigate the molecular mechanisms taking place at the interface to understand cohesive healing in these polymers. The quantification of self...

Self-healing processes in ionomeric elastomers

The use of dynamic bonds in self-healing polymeric systems allows restoring of the chemical structure and mechanical properties multiple times. In this respect, the use of ionomers represents a promising approach. The strong interaction between ionic moieties within a non-polar matrix leads to microphase separation and a behavior similar to...

Magnetic fluid bearings & seals: Methods, design & application

The bearing and the seal are two commonly used tribological components since nearly all moving machinery relies on them for proper operation. Even a small improvement in these components can have a big impact on both the market and the environment. The two main problems of these components are wear and friction. In addition, seals suffer from...
