Readily self-healing polymers at subzero temperature enabled by dual cooperative crosslink strategy for smart paint

Achieving the artificial supramolecular polymer with excellent low temperature self-healing capability has been a new topic of great significance in soft robotic actuators and smart coating. Nevertheless, the production of robust polymer with decent low temperature self-healing ability is severely impeded by its high crosslink density and low dynamic crosslink bond. Here, we report a design strategy that both low crosslink density and high...
