Poly(thioctic acid) materials exhibit excellent room-temperature self-healing properties due to their dynamic disulfide-bonded supramolecular network and have been widely used in applications such as wearable devices, adhesives, and wound patches. However, the limited mechanical properties of poly(thioctic acid) materials with dynamic supramolecular networks limit their practical applications. Therefore, there is an urgent need for a low-energy-consuming and facile method to enhance their mechanical strength and maintain their room-temperature self-healing properties. Here, a novel approach is developed by introducing Eu
