Adaptable Hetero Diels-Alder Networks for Fast Self-Healing under Mild Conditions

Adaptable Hetero Diels-Alder Networks for Fast Self-Healing under Mild Conditions

A novel adaptable network based on the reversible hetero Diels–Alder reaction of a cyanodithioester and cyclopentadiene is presented. Reversible between 50–120 °C, the adjustable and self‐healing features of the network are evidenced via temperature dependent rheology experiments and repetitive tens...

Zusammenfassung:A novel adaptable network based on the reversible hetero Diels–Alder reaction of a cyanodithioester and cyclopentadiene is presented. Reversible between 50–120 °C, the adjustable and self‐healing features of the network are evidenced via temperature dependent rheology experiments and repetitive tensile tests whereas the network's chemical structure is explored by temperature dependent 1H MAS‐NMR spectroscopy.
